hey there, poser-octane folks
I'm trying to figure out image-based lighting/HDRi. so, from what I understood, the renderer is analyzing an image and tries to imitate the lighting so that it will match the lighting that exist within the image, right?
so, IBL = infinite light, in a way, right? I have a few questions...:
1. If I want to integrate HDR light studio with my poser-->octane, which version should I get? (I'm getting a trial version. should it the stand-alone or the 3dsmax one?)
2. when I use HDRI, are there any rules as for matching the resolution of the .hdr file to that of the scene I'm rendering?
3. how does regular light emitters integrate with an IBL/HDRi lighting? if i want the general lighting to be IBL, but i want to create my own lights to control the shadows/highlights/catchlights etc, is that an option? are there any rules in terms of power setup? (I want to light with IBL but still have shadows cast with my other lights...i hope that makes sense).
4. is there a way to reduce noise without using the hotpixel removal (it makes the image very soft. all sharpness is gone...) ? more light?
feel free to suggest some good IBL/HDRi tutorials (gonna search youtube now).
thanks
