Modifing Evermotion Scenes in 3Ds Max deactivates Light Cache

[Agonywolf]

Hello.

 

I've been using 3ds Max for about a month now, and I'm still very new to it. I have a lot of trouble with it and runs very poorly on my system (lots of crashes).

 

I recently got Vray and some Evermotion scenes that require Vray. They render beautifully, but as soon as I modify them (importing OBJs, or even just moving around some of the pre-existing things in the scene) when I go to render, 3ds Max doesn't build the light cache before rendering anymore, and I get very very dark, ugly renders.

 

Here's an example of a scene rendered where all I did was move the camera location a bit:

 

 

And here it is after doing nothing but importing a simple object from DAZ | Studio, same render settings and all:

 

 

It's as if modifying the scene beyond camera position turns off the lights that make the render look so realistic. I can of course re-light these scenes, but I simply can't get them looking as beautiful as they started out.

 

I have discovered that I can "merge" in certain things and it will still render correctly, however if I attempt to save a copy of the scene, (so I don't write over the default that renders correctly) when I open said copy, it automatically renders incorrectly.

 

So basically I have to save a copy of the scene, arrange the things I want in the scene, open up the default file, merge in the objects I want, place the camera, then render. If the render goes sour and the program crashes, I have to do it all over again.

 

Can anyone tell me why this is happening? I'm sure it's just some simplt thing I don't know about. These scenes aren't much use to me unless I can put my Poser/Daz characters into them.

 

Infinite thanks from this noob for any help anyone offers.
