Hi guys, we are working on a brush painting tool in VR and we use RenderTargets for it. We have different sprays you can use to paint with different colors on the surface on a car mesh. It works great but we want to be able to save the result and load it again. At the moment we export the RenderTarget and save it on the disk. When you login next time we load the saved RenderTarget (we convert from .hdr to .png) as texture and draw the texture (as Material) to the RenderTarget. Our problem is that the image looses quality over time. Probably because of converting the image from hdr to png and loading it as texture and then drawing back to the RenderTarget.
The best solution would be to load the saved RenderTarget hdr image and directly initialize the RenderTarget with it. Has anyone an idea how to achieve this?
Thanks for your help,
