Hey, I wanted to ask something! This is my custom code for rendering OBJ meshes which works, with rethinking voxels it also recieves shadows, AO etc. I wanted to ask, is it possible to also bind the specular and normal maps? Can the shader work with that and use it (for example for screen space reflections and normal maps)? :)

@IMS Hello, given your bio I thought I might ping you for this :) Is it possible to bind the specular and normal maps alongside my rendering, aka do the shaderpack shaders have access to that?

IMS•14mo ago

sorry, didn't get to this

Sinan•14mo ago

No problem, thank you for answering

IMS•14mo ago

The way this is supposed to work is you use AbstractTexture's, and then you can just have _s and _n variants of those textures and Iris should just know how to use them

Sinan•14mo ago

May I ask in which sense? In my code above I do not render like normal blocks or items

IMS•14mo ago

so first try adding textures/re45_s.png any sense, it's caught at texture binding not at blocks or entities

Sinan•14mo ago

Yes, I have the _s and _n with new Identifier Oh okay, I never heard about AbstractTextures, I am scrolling through the docs but I am unsure on how to use them Nvm! So basically:

AbstractTexture texture_s = MinecraftClient.getInstance().getTextureManager().getTexture(new Identifier("luminance", "textures/re45_s.png"));

AbstractTexture texture_n = MinecraftClient.getInstance().getTextureManager().getTexture(new Identifier("luminance", "textures/re45_n.png"));
            RenderSystem.activeTexture(GlConst.GL_TEXTURE1);
            RenderSystem.bindTexture(texture_s.getGlId());
            RenderSystem.activeTexture(GlConst.GL_TEXTURE2);
            RenderSystem.bindTexture(texture_n.getGlId());

AbstractTexture texture_s = MinecraftClient.getInstance().getTextureManager().getTexture(new Identifier("luminance", "textures/re45_s.png"));

AbstractTexture texture_n = MinecraftClient.getInstance().getTextureManager().getTexture(new Identifier("luminance", "textures/re45_n.png"));
            RenderSystem.activeTexture(GlConst.GL_TEXTURE1);
            RenderSystem.bindTexture(texture_s.getGlId());
            RenderSystem.activeTexture(GlConst.GL_TEXTURE2);
            RenderSystem.bindTexture(texture_n.getGlId());

I should do this before calling draw?

IMS•14mo ago

no don't do anything with _s or _n pretend they don't exist, just have them Iris will grab them for you if you're registering them, also don't do that

Sinan•14mo ago

Oh uhm, I should just have them as files?

IMS•14mo ago

yep

Sinan•14mo ago

Woah I'm gonna give it a shot Hmm that did not seem to work, I will provide you with my code:

Sinan•14mo ago

First off I think this is what you meant?

IMS•14mo ago

yep

This is my render code:

This is all I do basically
