Hello..!! I have this weird issue and I was not sure whom to ask this either.. I wish you guys could help me.

Issue-1 : I have composed an interior scene in Sketchup 2017 and rendered using Interactive Rendering in CPU mode. in the final out-put the lights are fine, textures are fine and the output is great. But, when I use GPU acceleration the texture of the materials changes, few materials looses its properties and blacked-out in the final render and the lights become less intense so, in order to reduce my final render time I had to sit through hours changing all the material properties, light parameters again from scratch using interactive render now in GPU acceleration mode. Please help me with this issue. what should I do during modelling and texturing in order to get same results in CPU and CPU+GPU rendering scenarios.

Issue-2 : After I complete render with great detail and good colour contrast I shared my renders with the client. for my worst nightmare renders looked very pale and in slightly pink tone with very less and blury detail in clients computer. firstly I thought it was the issue with clients monitor settings later I opened the same renders in my mac book-pro and an iOS device and they looked utterly ugly in them too. But, the same renders looked beautiful in the primary system from which the renders are produced. I could not figure it out what went wrong. Please help me.
