Hi there, I was trying to use the rtt’s render result last frame as the input of this frame and this is what I’ve archived.
I met webGL error
GL_INVALID_OPERATION: Feedback loop formed between Framebuffer and active Texture. and I solved it by cloning the rtt with dynamicTexture and use dynamicTexture as input. However fps drops a lot with dynamictexture, so I’m wondering is there any effecient way to clone rtt?
