Environment Scale

Hi all

Hopefully this will be a quick one, I've just applied a spherical tif of a kitchen scene to the "refraction/reflection environment override" in VRay (Max 2012) and the scale of the image when I view it as a background is mahoosive (so not getting any reflection details on my model)!! Is there any way to scale the image down to suit the scale of my scene? Or is this limited to how the image was originally created?

Thanks in advance.

Environment maps have no scale, if you were to take a chrome sphere and put it inside another sphere with a texture on it and then rescale that second sphere and compare renderings the reflections would always be the same

You can just use an actual sphere geometry for this.

I could use a sphere, but I don't want to see the environment map in the render, I just want it to add some reflection detail. I've never been able to achieve good results for this utilising a sphere, but the Vray environment override usually works well. Thanks for the suggestion though.

Again, you can't scale an environment, the reflections will always be the same size. If you want to see more in the reflection you can tile it, but if it's an actual environment image then it won't look right that way.

BTW for a sphere option, you can set it not to be visible to the camera, it would still render in reflections though.

Just turn off the primary visibility, shadows, GI/FG, etc., for the sphere. Leave the relection settings only. This is what I do all the time. This way you can scale the environment map, so to speak.

Regards,
Mike
