HDR Lighting

Corona Corona for Cinema 4D General

On rotating an HDRI, the Offset U in the material tag would be used:

Let me know if that is not working for anybody!

Perfect - Thank you :smiley:

Spoke too soon…When I modify the Offset U I can see the HDR rotating in the CD4 Viewport, but when I hit render in Corona the viewport shows the HDR in the 0 degree position/default loading…so what I see in the CD4 viewport HDR wise is not the same as the VFB…I’ve even hit refresh and erase several times re-rotated the HDR and yet the VFB shows no movement.

Hmm, not sure on the cause of that, all is working here - the set up is a Sky object, with a Corona Material applied, with the HDRI in the Diffuse slot? Just checked in a simple new scene, and the update happens in the viewport, the C4D picture viewer, the rendered viewport and the Corona VFB. Also works if I set keyframes. Can you share the scene, or a simplified version of it?

Hi Yah Tom,

Just prior to knocking off for the night yesterday, I uninstalled Corona, reinstalled then pulled up the model I was working on. The model had already been rendered prior in Thea, so what I did was remove all materials, camera settings etc etc and started with a bare model, applied a general corona diffuse material to everything, recreated the sky as per movie and now everything’s working as expected !!!

So not sure if it was the reinstall, or something carrying over from Thea but what I’ll do is pull up some more models I’ve worked on and see what happens.

Thanks for getting back so quick :smiley:

Glad to hear all is working now! NP too, just glad it helped resolve it!

why don’t you just rotate the sky object. It’s much more intuitive to me.

Thanks for that video - real helpful, real clear.
I’d like to see 50 videos like that - each 5 to 10 minutes long. A list that a user could access and get a quick primer on a subject when needed.

Is there a way to adjust the HUE value of an HDR map? I have an HDR map I like, but would like to remove some of the green that it contains.

Put it into a “filter”. You know, click the arrow by the name → filter :smiley:

Hope thats whats you meant.
