Differences Between Rendered Window in Batch Render and Single Render

[erickdt]

In an effort to streamline workflow here in my office between exhibit designers and graphic designers we have begun exploring the idea of the graphic designers creating their graphic elevations within MAX as opposed to basically tracing over screen grabs from AutoCAD which is very time consuming and not very accurate. To that end, I have been working on a renderings preset for rendering our these graphic elevations. The basic setup disables glossy effects and all lights under global switches and uses the "default lights off with GI setting". Also, indirect illumination has been disabled. These settings are combined with the VRay toon rendering effect to create a crisp and concise graphic elevation without having to take time to calculate indirect illumination etc. This setup produces exactly the result I want when rendered camera by camera from the standard rendering setup dialogue. However, when I try to batch render the same views with the same exact settings the result is entirely different. Does anybody know how I can fix this or what is causing it?

Any ideas anybody? I'm going out of my mind as to what the problem is here...

Ok so after doing more research I've found that this is an issue with the defaults lights. What I'm not understanding is why the default lights would change when I'm doing batch rendering. Any ideas?

You used gamma different from 1 ?

No. I'm using lwf. Its definitely a default lights issue. Like I said, I can't figure out why they'd change when batch rendering as opposed to rendering camera by camera.
