Here are three renders of the exact same scene. The first has an environment map applied the next has it disabled and the third has the environment map but no glass plane. I can’t quite figure out why the combination of the glass plane (which has thin geometry glass arch & design material applied to it) along with the environment map seem to create an odd green artifact. The other glass plane next to it is exactly the same but does not have the same effect and when Im remove the glass plane altogether there is no artifact. There are no polygons on top of eachother. What’s going on here?

(The scenes are all rendered using mental ray with FG set to draft. The scene is lit with an mr area spot and an mr area omni)

Any help would be much appreciated.

Thanks
Dan

Here’s a new scene with the environment map applied and a plane (with a thin geometry arch & design glass material applied to it) covering most of the view (apart from a small strip along the top). The second image is the map by itself.

Is this a bug? Any ideas?

Can you just post the second scene as a zip file with your settings?  Indicate which version of Max also. Replace your enviromnet map with a standard map that ships with Max, and confirm the problem green splotch still happens before up loading… or if the map is small enough, just include your current map in the zip or rar file.

I have a suspicion that in the Advanced Rendering Options rollout, either in Reflections or Refractions section, you have a color in the Max Distance Fade to end color slot.  It’s discussed in the Arch and Design Material (Mental Ray) topic in Max Help.

Thanks for replying Maneswar… I’ve been pulling my hair out over this one. It seems to have everyone stumped. I checked the max distance colour in both reflection and refraction but neither have the colour changed and both are disabled.

I have winrar but have never zipped a file before. Can I use winrar to do it?

I believe winrar can produce zips. If not then a .rar should work (but is not the preferred format for attachments).

Thanks Steve. I’ll give it a shot

Attached is a .zip of a max scene with plane with thin geometry glass arch & design material applied in front of the environment map that I’ve been using in my other scene. The actual environment map .jpeg is also in the .zip.

Dan, it is rendering correctly here… based on your test scene.  The problem may be related to the FG… but I added an MR Omin and an MR Spot and enabled FG Draft, and that too rendered cleanly too.

Please post a scene where when you hit render, it gives you that green tint.  Is the test scene such a scene?

That’s bizarre. That exact scene renders with the green splotch on my pc. I’ve attached a render that I did just now using that test scene without changing any parameters.

I’m using a student license but that shouldn’t impact on a render… should it?

I’m so confused

Works perfectly here on both 32 and 64 bit versions. Are you having any other problems or is it just this one scene? Could be a setting which is “global” i.e.not saved in the scene, though I have no idea what.

The license is immaterial - it’s the same software regardless of which type of license you have.

Just this scene. However, this is the first scene in which I’ve used an environment map.
