Render Target is not working for the model

[rebel1324]

I was able to make it work in 3d2d but I can't really get it work with the model.
Help me lua kings!

Are you getting any errors? This function should be giving you some:
[lua]function freeRT(rt)
if (RENDER_TARGET_SCREENS[id] == rt) then
RENDER_TARGET_SCREENS[id] = nil
end
end[/lua](id is nil)

Currently It's not about Freeing RT.
It's all about applying Lua-Generated Textures/Materials to the Model.

apparently it's okay to read a nil index of a table... I have no idea why. Nevermind.

Can you be more specific instead of just a code dump?
