A couple of things

- it looks like you have multiple faces one on top of the other which is leading to 'z-fighting', https://en.wikipedia.org/wiki/Z-fighting

- the 'recommended' version of forge has a bug where the vertex order of faces in obj files doesn't match what vanilla expects for ambient occlusion and leads to strange lighting.  Try latest instead of recommended.

I use 1.15.2-31.1.63 forge version

And the problem was that this obj files is too large and render for all 8 blocks... 

Can I change the start position from which it will be loading obj model?

Hi

I think it's better to split your obj file into 8 separate files.

 

If you really want to load just a small part of one obj file, have a look at OBJLoader and OBJmodel to see how it parses the file (g and o in particular); you can copy it to your own loader class and tweak it if you want to.

I wanted it over json, but ok...

Any good way to split a model? Or will I have to do it for each file separately?

    • Hello! I'm trying to get a list of all entries registered in the infusion upgrade registry. Code can be found in github: https://github.com/ChamoisEST/MiningMadness/tree/1.20.1 Registry in common/registries/MMRegistries.java Event that calls the registry is in MiningMadness.java List of registered entries should be called in common/capabilities/infusion/InfusionCapabilityImplementation.java:getActiveInfusions() in the for loop. Is there any way to accomplish that? Thanks in advance!

    • Hi. I'm trying to play RLCraft with Optifine but my game keeps crashing on startup with Exit Code 1. The modpack was working fine yesterday, not sure what changed to make it not wanna work anymore. I was hoping someone here could help me figure out what's going wrong. If I remove Optifine, nothing changes, I still get the same errors. Thanks in advance. Crash Report (I only included the errors+fatal, I’m not sure if more is needed, please let me know): https://pastebin.ai/66ivknz0f4  
    • I am trying to port my mod from 1.20.2 to 1.21, but I am encountering difficulties regarding the classes for rendering the GUI and related events. What are the equivalents of the following classes? net.minecraftforge.client.event.RenderGuiOverlayEvent net.minecraftforge.client.gui.overlay.NamedGuiOverlay net.minecraftforge.client.gui.overlay.ForgeGui net.minecraftforge.client.gui.overlay.GuiOverlayManager net.minecraftforge.client.gui.overlay.IGuiOverlay   thx
