Environment Light - recommended map file projection mode

Unread postby machieb » Tue Feb 25, 2020 11:22 am

Hello,

can someone please tell me, what the recommended map file projection mode is, for an environment light using a HDRI?

I am unsing a free studio HDRI from HDRI Haeven (https://hdrihaven.com/hdri/?c=studio&h=studio_small_03).
With the projection mode "UV" and "Parametric" in the map file projection mode, overall lighting is brighter than with the environment projection mode. (See Attachment: Clarisse_with_uv_projection.jpg)
With the "Environment" projection mode the HDRI lighting is darker. (See Attachment: Clarisse_with_environment_projection.jpg)

The Clarisse wiki says about the environment projection mode: "The Environment projection mode projects the map on an infinite sphere".
Sounds good to me?!
I testet the same setup in another dcc with another renderengine and get equal results like the UV projection. (See Attachment: DCC_HDRI_render_result.jpg)

Maybe someone has experience and can tell me which projection mode is recommended to use in clarisse?

The second thing is, that with the environment projection mode on, the viewport gets no update when rotating the environment light. When in uv projection mode, the viewport updates when rotating the environment light. Maybe a bug?

Hi,

To use an HDRI map on an environment light, just use parametric projection.

The Environment projection mode projects the map on an infinite sphere whatever the support in World. So any transform can't affect this projection. The environment projection is not mean to be used with lights.
