Topic category: Feature requests and ideas for MCreator
The GlStatemanager for Minecraft is an advanced topic, and I do not think It would be possible to allow for everything to be done with it without code, however, I would at least like to see some kind of support for it, for example: Effect creator/manager
Allows for a texture input that will be mapped to surfaces made in the effect creator/manager. The effect could then be translated rotated or scaled in a procedure later.
With this you could make block effects like a color changing glowing cube around a block as well as many more things.
