Weird grass texture when rendered in Cycles #413

Closed DraxDoomer closed 1 year ago

DraxDoomer commented 1 year ago

Did the issue happen after restarting Blender?

Check known issues

What happened?

Ive had this problem for a while when I am trying to make a barebones mc world for an animation and renders. This happens after I change the textures of the mineways imported world to use the barebones texture pack using the "Swap Texture Packs" features on mcprep. The grass looks fine when unrendered but when rendered in cycles it looks weird (look at screenshots). It seems to be fixed when I delete a grass face that seems to be duplicated but doing that for a lot of grass is going to take ages. How do I fix this?

Unrendered: grassunrendered

Rendered: grassrenderedproblem

What steps are needed to produce the bug?

1) I imported the world using Mineways 2) I MCPrepped the world 3) I selected the world and click the "Swap Texture Pack" button on MCPrep and then went into the barebones texture pack file 4) I rendered the scene in Cycles

What version of MCprep are you using?

MCPrep v3.4.3

What version of Blender are you using?

Blender 3.4

It's a known issue with Mineways OBJs in Blender, just do the following:

MCprep doesn't do this to avoid users using lower end hardware from going "why is MCprep taking so long" or "Blender keeps crashing"

Ah i see

And I did what you suggested and I still have the error, sorry

StandingPadAnimations commented 1 year ago

Yeah then there's not much that can be done. This is more of a Mineways issue rather then an MCprep one.

Personally, I would suggest using jmc2OBJ, since that tends to have less of these issues.

Aw welp. Thx for the help anyways

I want to use jmc but for some reason it won't work on my computer. Apparently just when I run jmc, it seems to be using up a lot of ram when its not supposed to. But ye I know I should not discuss this too much here since this is supposed to be related to MCprep.

StandingPadAnimations commented 1 year ago

Just curious, are you using the Java installation from java.com? If so, then jmc2obj will only have access to 4 GB of RAM, hence why it may seem like it's using a lot when it actually isn't.

Try Adoptium, which are OpenJDK builds provided by the Eclipse Foundation: https://adoptium.net/temurin/releases

If given the option to select between Hotspot and OpenJ9, choose Hotspot for compatability reasons (before you ask, Java is more like C and C++ in implementation these days, in that there's a standard and people make "implementations" according to that standard).

Yeah i just realised yesterday i have been using 32-bit java which only allocates 4GB of ram. I downloaded the 64-bit version from the java website itself and now jmc is working.

Thx for helping anyways.
