Isn't a Size (radius) option needed for HDRI environments?

[Micha_cg]

Hi,

my impression is, that the lighting per HDRI environment need a size option for the "HDRI sphere", because for simulating small light tents like used for jewelry, the light distribution of the current infinite environment sphere is looking wrong.

Example: a HDRI show a single light from the top and is lighting a ground plane (diameter 1m). If the HDRI sphere is infinite, there is 100% homogeneous lighting on this ground plane. If the environment could be set to a radius of 1,2m, than caused by the falloff, the ground would show a brighter inner area. (I hope my explanation is good enough to show the problem.)

Could it be possible to get an option for the environment size?

Ciao,
Micha

I tested it with a sphere and HDRI emitter texture ... and found no difference in the look for different sphere sizes. So, this idea can be forget.

yeah, we throw away the viewport geometry that we make. We just make the dome the size of the scene bounding box. We tried to copy the way it's done in Max as best we could.

It's reported yet, so only for keeping the eyes on it - the dome light need two little features - invisibility for the alpha and wire frame mode per default like all other lights.
