is there any way to do this…

basically, i rendered out an environment in VUE6i as a spherical panorama, it contains a sort of fantasy sky with a roof of fast moving clouds, the light pulses with music and is occluded by the clouds occasionally. i want to use that as the IBL model and for raytraced reflection, but i can’t see that there’s a way to specify a sequence of HDR images.

is there a way to convert a bunch of HDR’s into a movie file that is HDR? will EIAS read that?

AE CS3 only generates an HDR sequence of stills...so that won’t work....

how difficult would it be to make EIAS allow for a sequences of stills?
is this a feature coming in v8?

This is definitely possible.
The hdr’s need to be numbered sequentially (filename0001.hdr, filename0002.hdr, etc)
When you add the hdr map check the “use multi-frame files” box in the open dialog- and select the first image in the sequence.

I have tested this myself- and it will work

However- the GI sampling tends to be very noisy, so use lots of samples. You will often get “flashes” of light and dark between frames, too, so your mileage will vary depending on the sequence itself, and your GI settings.

Good luck-

I would be really interested in seeing your tests

Hi All

It’s possible to have a different .hdr texture for every frame, but, at least in theory, such animated illumination should be flicked/unstable if “Adaptive Sky Map” is ON - just because “adaptive” works so

oh yeah...duh…

sheesh...that’s what happens when you are going too fast in too many different directions…

so i guess it would be better to use an LDR sequence for illumination and an HDR for raytrace reflections/refractions…

thanks for the advice Dave and Igors!
