Hey all,
I am in the process of getting up to speed in Octane, and I am encountering a few problems. I have tried a number of google searches trying to sort out some of the issues I am having but so far to no avail. I am fully cognizant that I may just being doing something wrong, or that my expectations on how somethings are intended to work are incorrect, however I have yet to find someone who who can tell me what I am doing wrong if at all. In an effort not to spam the board with my first post, I have put everything I am having trouble with into one post.
1) Camera Projection (ie. Front Projection Image Mapping) why does it seem to not work quite like I would expect. I am for example able to Pan the Camera Around inside the image and see where the image ends etc, which seems counter intuitive if for example you are trying to render out CG inserted into tracked footage. And often times I will turn it on, and the image will be upside down and looking like a spherical mapped image, rather than something that fits to the camera space, or some kind of planar image that tiles into infinity, and yes this is using the Camera Projection Node slotted into the Projection input in the texture I am using. In Lightwave For example if I move the camera around the image I am trying to composite into stays locked to the camera. I have talked to a few of my friends who use Octane, and neither of them seemed to have an answer.
2) Rendering TFD sequences out of LW using Octane. It either crashes out right, or simply does not load the next Cache file in the sequence. I have tried it with both my own sim in the scene I am working in, and the content provided by OTOY. I have only gotten it to work once with a default sim in an empty scene. Nothing that I can actually use. The cache looks fine in the IPR, and updates when I change frames, but not at render time (F10). I have tried this both on my network and off, and neither seems to help.
3) texturing TFD Caches seems hit and miss, I can't seem to get a predictable result. I have tried to use for example to use the content provided by OTOY on my own sim, and it looks wrong. For example on the Otoy content it looks like normal fire, but on my sim it looked like it was blue flame instead. Weird stuff like that.
4) I am having trouble lighting a scene, using IBL but being able to have a particular mesh or material not accept the direct influence of say the environment. For example I have a space ship that is sitting in water on a lake, and I want to light the ship, but not have the light from the environment shot up on the water material because that already exists in the image, and it just doubles up and looks wrong. I just need the lit reflection of the space ship on the surface of the water for compositing purposes.
I can record videos showing these issues if necessary, however I am hoping someone can point out what I am doing wrong in each of these cases.
Thanks to anyone in advanced for any assistance you can render.
