[1.7.10][Solved] Render texture on inner side of block

[Niverton]

Hey, I made a block with a transparent texture on the sides, but it looks ugly because it doesn't draw the textures on the inner sides :

(I overrode the isOpaqueCube function to return false so it renders block that are next to mine)

Is there a way I can render a texture inside the block ?

[Niverton]

I just tried, it doesn't work

 

@Override
public boolean shouldSideBeRendered(IBlockAccess p_149646_1_, int p_149646_2_, int p_149646_3_, int p_149646_4_, int p_149646_5_) {
return true;
}

 

 

I'm guessing it's because the textures are drawn on planes, which only have one side rendered

You have to use a tessellator. I cant think of any other way to do this

Hi

 

I think you can achieve this by rendering your block in pass 1, which turns off back-face culling  - Block.getRenderBlockPass() or Block.canRenderInPass().  It also turns on alpha blending but if you set your alpha to 1 it won't look any different.

Thanks everyone, I tried to use a custom renderer with a tessellator, couldn't really get how I was supposed to do it, so I tried TGG's solution, and added this to my block's class

@Override
public int getRenderBlockPass() {
return 1;
}

@Override
public boolean canRenderInPass(int pass) {
return (pass == 1)? true : false;
}

 

But I don't think I'm doing this right, and it didn't change anything

Hmm that should have worked.  Perhaps I'm wrong, I last tested it in 1.6.4 I think.

 

Instead, you could use an ISimpleBlockRenderingHandler and use GL11.glDisable(GL11.GL_CULL_FACE), then call the vanilla block rendering method, then change CULL_FACE back again.

Hey, thanks for the link ! I was curious and looked at your blog, found this very interesting post on the Tessellator. It explains everything I need, I'll try again using the Tesselator because it's really interesting and I might need it later on. Thanks a lot !

[Niverton]

Alright, spent a lot of time on this thing, but it was worth it !

Had some problems too with the render in inventory, thanks again TGG found a solution of yours on another topic. My block looks really nice now

Code for my renderer, not really commented but you can find anything you need on TGG's blog
