Does anyone know how to send the contents of a texture to itself? Something like this:
const imageTexture = new ProceduralTexture('image', 512, 'image', scene, null, false, false);
imageTexture.setTexture('sameTexture', imageTexture);
(it fails with “Feedback loop formed between Framebuffer and active Texture.”)
May be there is a solution with RenderTargetTexture ? But I don’t know how to do it right 
You can’t because of the feedback loop 
you have to use an intermediate texture to store it (The good idea is to use a PassPostProcess to duplicate it on the GPU)
seems like I did it, but do not think it’s in an optimal way

any suggestions how to improve it? BTW did not figured out how to use PassPostProcess 
Hm but why not use customMaterial and use method addUniform(‘diffuseTexture’, ‘sampler2D’), or perhaps use shaderMaterial…proceduraltexture has been there for a while not sure if it’s still being maintained
Cheers!
