[1.5.2] Obj rendering - doesn't render

Recommended Posts

I've been trying to figure out how to render obj files into minecraft. I've gotten it to render as an item but it just won't render as a tileEntity. Here is a github link to my testing mod. Any idea why it's not rendering?

Also note that I've registered the item renderer and tileEntity renderer in the ClientProxy.java.

	int scale = 1;

GL11.glPushMatrix();
GL11.glDisable(GL11.GL_LIGHTING);

// Scale, Translate, Rotate
GL11.glScalef(scale, scale, scale);
GL11.glTranslatef((float) x, (float) y, (float) z);
GL11.glRotatef(-90F, 0F, 0F, 0F);

FMLClientHandler.instance().getClient().renderEngine.bindTexture(Textures.MODEL_BUSWAY);

model.renderPart("test");

 

use glTranslated instead of glTranslatef

model.render(), instead of renderPart(String), the part "test" might not exists

Oh I know that the part "test" is there, it's listed in the obj file. Also I'm using renderPart in the item renderer too and it's working.

 

Here is the obj file for reference:

I just figured it out. I changed this:

GL11.glRotatef(-90F, 0F, 0F, 0F);

to this:

GL11.glRotatef(0F, 0F, 0F, 0F);

This is what was causing the problem. The -90degree rotation made the model invisible or unrenderable. And it also seems that I pre-rotated the model in the export options in blender so it wasn't needed in the first place.

 

Anyway thanks for responding.

no actually its because you rotated with a weird quaternion, resulting the messing up the model completelly

 

GL11.glRotatef(-90F, 0F, 0F, 0F);

 

this is useless and will probably f up your model

 

GL11.glRotatef(-90F, 0F, 1F, 0F);

^ this will rotate the model

I see now. The first variable sets the rotation angle and the other vars are for telling what axis to rotate on.

 

Anway I got the Testing renderer working on the test mod, but the main mod isn't rendering what I want to.

 

 

Renderer:

package altenergy.client.render.tileentity;

import java.util.Random;

import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;
import net.minecraft.tileentity.TileEntity;

import org.lwjgl.opengl.GL11;

import altenergy.client.model.ModelEnergyBusway;
import altenergy.content.conductors.TileEnergyBusway;
import altenergy.lib.Textures;
import cpw.mods.fml.client.FMLClientHandler;

public class TileEntityEnergyBuswayRenderer extends TileEntitySpecialRenderer {

private ModelEnergyBusway model = new ModelEnergyBusway();

private int random(int maxNum) {

	Random randNum = new Random();
	return randNum.nextInt(maxNum);
}

public void renderModelAt(TileEnergyBusway tileEntity, double x, double y, double z, float tick) {

	float scale = 1;

	GL11.glPushMatrix();
	GL11.glDisable(GL11.GL_LIGHTING);

	// Scale, Translate, Rotate
	GL11.glScalef(scale, scale, scale);
	GL11.glTranslatef((float) x, (float) y, (float) z);
	// angle, xaxis, yaxis, zaxis
	GL11.glRotatef(0F, 0F, 0F, 0F);

	// Bind Texture
	// bindTextureByName(Textures.MODEL_BUSWAY);
	FMLClientHandler.instance().getClient().renderEngine.bindTexture(Textures.MODEL_BUSWAY);

	boolean[] connectedSides = tileEntity.visuallyConnected;

	if (connectedSides[0]) {
		model.renderPart("BuswayConnectionF");
	}

	if (connectedSides[1]) {
		model.renderPart("BuswayConnectionE");
	}

	if (connectedSides[2]) {
		model.renderPart("BuswayConnectionA");
	}

	if (connectedSides[3]) {
		model.renderPart("BuswayConnectionB");
	}

	if (connectedSides[4]) {
		model.renderPart("BuswayConnectionC");
	}

	if (connectedSides[5]) {
		model.renderPart("BuswayConnectionD");
	}

	model.renderPart("BuswayNone");

	GL11.glEnable(GL11.GL_LIGHTING);
	GL11.glPopMatrix();
}

@Override
public void renderTileEntityAt(TileEntity tileEntity, double x, double y, double z, float tick) {

	renderModelAt((TileEnergyBusway) tileEntity, x, y, z, tick);
}
}

 

TileEntity:

package altenergy.content.conductors;

import net.minecraft.tileentity.TileEntity;
import net.minecraftforge.common.ForgeDirection;
import universalelectricity.core.block.IConnector;
import universalelectricity.core.block.INetworkProvider;
import universalelectricity.prefab.tile.TileEntityConductor;
import altenergy.lib.Reference;

public class TileEnergyBusway extends TileEntityConductor {

public TileEnergyBusway() {

	channel = Reference.CHANNEL_NAME;
}

@Override
public double getResistance() {

	return 0;
}

@Override
public double getCurrentCapcity() {

	return 5000000;
}

public int getNumCon(boolean[] connections) {

	int count = 0;

	for(int side = 0; side < connections.length; side++) {
		if(connections[0]) {
			count++;
		}
	}


	return count;
}

public void printConnections() {
	System.out.println("Bottom: " + this.visuallyConnected[0]);
	System.out.println("Top: " + this.visuallyConnected[1]);
	System.out.println("Front: " + this.visuallyConnected[2]);
	System.out.println("Back: " + this.visuallyConnected[3]);
	System.out.println("Left: " + this.visuallyConnected[4]);
	System.out.println("Right: " + this.visuallyConnected[5]);
}

@Override
public void updateConnection(TileEntity tileEntity, ForgeDirection side) {

	if (!worldObj.isRemote) {
		if(tileEntity instanceof TileEnergyBusway) {
			if (tileEntity instanceof IConnector) {
				if (((IConnector) tileEntity).canConnect(side.getOpposite())) {
					connectedBlocks[side.ordinal()] = tileEntity;
					visuallyConnected[side.ordinal()] = true;

					if (tileEntity.getClass() == this.getClass() && tileEntity instanceof INetworkProvider) {
						getNetwork().mergeConnection(((INetworkProvider) tileEntity).getNetwork());
					}
					//System.out.println("Connection Complete");
					//printConnections();
					return;
				}
			}

			if (connectedBlocks[side.ordinal()] != null) {
				getNetwork().stopProducing(connectedBlocks[side.ordinal()]);
				getNetwork().stopRequesting(connectedBlocks[side.ordinal()]);
			}
			connectedBlocks[side.ordinal()] = null;
			visuallyConnected[side.ordinal()] = false;
		}
	}
}
}

For some reason the connectedSides array when the tileEntity is place down doesn't seem to see or connect to the tile entity's visuallyConnected array. So that when I have placed two blocks next to each other the renderer is suppose to render one of the BuswayConnection's but isn't. I've tested all the parts and they all work just fine. It's just the instance of tileEnergyBusway isn't sending the visuallyConnected boolean array. At lest that's what it seems like.

 

I'm using the Universal Electricity api for the electric network.

    • Hello, Hi and I am making a forge 1.12.2 mod and also trying to get a custom model helmet item (I made a joker mask) and exported it to .json format and put it in the ~/namespace/models/item folder. Though, I'm struggling to get the item to render what I want it to be rendered like as I've positioned it in the 'head' window view in blockbench. How did you render out your model? I checked your code and it looks like no references to the actual model are being made. I'm new to this forge modding stuff (was a fabric modder) and I desperately need some help. Is there a way to standardly render out armor models made using blockbench? any methods that one can use? My model in JSON: ```json { "credit": "Made with Blockbench", "texture_size": [160, 160], "textures": { "0": "ydyrn:items/joker_mask_texture", "particle": "ydyrn:items/joker_mask_texture" }, "elements": [ { "from": [0, 0, 0], "to": [16, 16, 1], "faces": { "north": {"uv": [0, 1.7, 16, 14.2], "texture": "#0"}, "east": {"uv": [0, 4, 0.9, 5.6], "texture": "#0"}, "south": {"uv": [0, 5.8, 1.6, 7.4], "texture": "#0"}, "west": {"uv": [0, 1.9, 1.3, 3.5], "texture": "#0"}, "up": {"uv": [0, 3.4, 1.6, 4.2], "texture": "#0"}, "down": {"uv": [0, 9, 1.6, 9.7], "texture": "#0"} } }, { "from": [15.8, 11, 0.5], "to": [16.2, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"} } }, { "from": [0.2, 11, 14.6], "to": [15.8, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 9.46, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 9.46, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 9.46, 7.94], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 9.46, 7.94], "texture": "#0"} } }, { "from": [-0.2, 11, 0.5], "to": [0.2, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"} } } ], "display": { "thirdperson_righthand": { "translation": [-0.25, -2.75, 0], "scale": [0.3, 0.3, 0.3] }, "thirdperson_lefthand": { "translation": [-0.25, -2.75, 0], "scale": [0.3, 0.3, 0.3] }, "firstperson_righthand": { "rotation": [-9, 115, 15], "translation": [0, 1.25, -1.75], "scale": [0.5, 0.5, 0.5] }, "firstperson_lefthand": { "rotation": [-9, 115, 15], "translation": [0, 1.25, -1.75], "scale": [0.5, 0.5, 0.5] }, "ground": { "rotation": [40, 0, 0], "translation": [0, -2.5, 0], "scale": [0.5, 0.5, 0.5] }, "gui": { "rotation": [0, 180, 0] }, "head": { "translation": [0, 0, 0.25], "scale": [0.82773, 0.73594, 0.9] }, "fixed": { "translation": [0, 0, 8.75] } }, "groups": [ 0, { "name": "straps", "origin": [0, 0, 0], "color": 0, "children": [1, 2, 3] } ] } ```
