3. Modify Define symbol

If you are using UniVGO 2.5.0 or lower, modify the define symbol to match the version of VRMShaders (com.vrmc.vrmshaders) you are using.

Unity Editor

Menu Bar > Edit > Projcet Settings

Projcet Settings Window

Player > Other Settings > Script Compilation > Scripting Define Symbols

Add the Define symbol to match the version of VRMShaders (com.vrmc.vrmshaders) you are using.

symbol value	min version	max version
VRMC_VRMSHADERS_0_72_OR_NEWER	0.72.0	0.78.0
VRMC_VRMSHADERS_0_79_OR_NEWER	0.79.0	0.84.0
VRMC_VRMSHADERS_0_85_OR_NEWER	0.85.0	0.103.0
VRMC_VRMSHADERS_0_104_OR_NEWER	0.104.0	0.124.2
