I am using an IBakedModel to render an OBJ(it's meant to be animated but that's a struggle for tomorrow), but in  game it renders black, when the texture is bright blue and white.

try set isOpaqueCube = true

in block class.

No change

I remember reading that obj need to have proper normal /texture mapping .

I believe I exported with normals written(it was a little while ago)

I re exported with normals, no change. Unless you meant something else?

Try flipping the normal's your model in the modeling package you are using. If it was an OpenGL texture issue then the model would be either white with a gradient from the normals or it would have another textured being displayed on the mesh because glBindTexture(GL_TEXTURE_2D, ...) wasn't passed zero to unbind the texture.

I was thinking of uv texture mapping . When you add a texture to a 3d model and you kinda pick and choose where it goes. All objs used with MC need to have proper uv mapping done. Then when you place a texture on them they will texture themselves the same way you picked. If you never done the uv map is likely the object will look black.  Maybe

UV map is in place in the above picture.

No dice, still black

Not sure at all that this will work, but I did see a public method in the

BlockModelRenderer

yesterday called

renderModelBrightness

. What happens if you call this instead of using the tessellator? (renderModelBrightness does a few jumps, and at last lands on renderModelBrightnessColorQuads which seems to draw the model for you (remember to translate the model to where you want it before doing this!))

The call would thus be

Minecraft.getMinecraft().getBlockRendererDispatcher().getBlockModelRenderer().renderModelBrightness

Pass

true

for the last boolean btw. If false, it seems to color... the model with the value of the passed brightness...

 

I'm not stating that this will work. I'm working on the tangent that your model has no brightness = renders completely dark. If that's incorrect, well then, then we know that is not the case.

We get an error now!

That one is obvious, since BlockModelRenderer#renderModelBrightness will call VertexBuffer#begin() in its own, you shouldn't call the begin method yourself. Same will apply for Tessellator#draw().

It seems that there's problem with lighting texture settings while in the TESR.

Thank you abastro! Silly me.

Well now it's invisible

GlStateManager.enableLighting();
        GlStateManager.pushMatrix();

        GlStateManager.translate(.5, 0, .5);
        long angle = (long)te.angle;
        GlStateManager.rotate(angle, 0, 1, 0);

        //RenderHelper.disableStandardItemLighting();
        this.bindTexture(new ResourceLocation("labstuff:textures/models/solenoid.png"));
        int bright = 0xF0;
        int brightX = bright % 65536;
        int brightY = bright / 65536;
        OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, brightX, brightY);
        if (Minecraft.isAmbientOcclusionEnabled()) {
            GlStateManager.shadeModel(GL11.GL_SMOOTH);
        } else {
            GlStateManager.shadeModel(GL11.GL_FLAT);
        }

        World world = te.getWorld();
        // Translate back to local view coordinates so that we can do the acual rendering here
        GlStateManager.translate(-te.getPos().getX(), -te.getPos().getY(), -te.getPos().getZ());

        Tessellator tessellator = Tessellator.getInstance();
        Minecraft.getMinecraft().getBlockRendererDispatcher().getBlockModelRenderer().renderModelBrightness(getBakedModel(), world.getBlockState(te.getPos()), bright, true);

        //RenderHelper.enableStandardItemLighting();
        GlStateManager.popMatrix();

found it! Now to solve the texture(it's currently stark white)
