I miss ISO and shutter speed controls at camera parameters.
There's a Maxwell rollup for the normal Max cameras, just go to the modifiers panel and scroll down. By default the rollup is below "depth of field parameters". It might be a bit confusing as the rollup doesn't show up until you create the camera in the scene, but this is a Max limitation.
-At the material browser when searching for a folder it doesn't display two mapped network units that I have. I can reach them through the network but they should look like another drive.
We'll look into this.
-When translating standard materials form max chaging opacity produces strange results.
We're testing it now, but can you be a bit more specific than "strange"? :)
-When changing tiling from the bitmap controls it actually tiles the texture, but the render doesn't match what is displayed at the screen (looks like 3dsmax tiles fixing the texture at the middle and maxwell fixes it at the corner).
We'll investigate.
-The invert texture tick works but not most of the rest at the output rollout.
The Maxwell renderer doesn't support the other kind of image manipulation functions that are present in that rollup. This is not a plug-in issue.
