mme_worldShader "shaderName"
Try with build-in shaders: mme_worldShader "mme/green".
P.S.: hope Bambi is alright now.
This changes everything! Bambi didn't actually know this was possible! Bambi needed a green screen so much! See, the best thing Bambi could come up with was filming the scene with different characters multiple times with the same camera (X;Y;Z) positioning settings and masking every frame of that footage. It would take forever!
All Bambi has to do now is re-capture with the green screen on and chroma key the shit out of it!
Thanks to you, lost Bambi has finally found its home! Bambi is now at peace!
