Cannot render volume

[EmptyBlueBox]

Hi! I'm using your tool to visualize some bvh files! I'm using MacOS with M1Pro chip.

Everything went on smoothly, except I couldn't visualize the colored volume around the skeleton, and there seems to be a white box around the skeleton.

However, when I turned down the opacity a little bit (from 1 to 0.99), the white box disappeared but still no colored volume around the skeleton. Input multiple bvh files does help.

Thank you in advance!

This looks like a shader issue. Are you able to compile in debug mode and then share the log?

The above images were already compiled with BUILD_MODE ?= DEBUG. I think this is because the shader version.

Are you also compiling raylib from scratch? I wonder if you need to make sure you compile it with a particular GRAPHICS variable to make sure that glsl version is supported:

[EmptyBlueBox]

Yes, I make clean and compile them again, still got problems. Maybe some problem like this one? But I'm not familiar with these tools :(

[orangeduck]

Perhaps try switching the version to 330 non-es.

#define GLSL(X) \
  "#version 330\n" \
  GLSL_DEFINE(AO_RATIO_MAX) \
  GLSL_DEFINE(AO_CAPSULES_MAX) \
  GLSL_DEFINE(SHADOW_CAPSULES_MAX) \
  GLSL_DEFINE(PI) \
  #X

[EmptyBlueBox]

That works! Just change #version 300 es to #version 330 will work!

Great, I am glad to hear that worked :)
