Compatibility with (my own) custom renderers

[zabijakmensin]

Hello,

I’m developing a physics mod using PhysX JNI. To render physics actors, I register a WorldRenderEvents.AFTER_ENTITIES listener, iterate through all actors, and submit their geometry to the entityCutoutNoCull() RenderLayer (using the BufferBuilder from the WorldRenderContext). This works fine - the actors render correctly, and lights themselves render as expected.

However, I'm running into an issue where Veil’s lights don’t interact with my physics actors at all. Light passes through them completely - no shading, no occlusion, nothing - unlike Minecraft’s entities or blocks, which the light renderer interacts normally with as expected.

I’m assuming this happens because Veil doesn’t know my geometry exists - since I’m just manually pushing vertices and not registering anything in its pipeline. Is there a way to make Veil “aware” of my objects so that lighting affects them properly? Or is there a workaround to integrate custom geometry like this into its lighting system?

For context, my physics actors are completely separate from Minecraft's Entity or EntityRenderer<?> classes - they’re standalone objects with their own renderer logic.

I’m using Fabric 1.21.1 and Veil 1.0.0.234. I also have 0 experience with shader/light pipelines in general, so apologies if I’m missing something obvious.
