Is there a way to make octane works with RPC at all..?

well, the only problem I see is direct light not going thru transparent materials, hence showing an "square" shadow, so there is several things you could do, the first would be using an HDRI image as enviroment, your shadows would show as expected (but in most cases HDRI throw soft shadows instead of sharp ones), another thing would be instead of using a plane, doing a rough polygonal cutout of the image so the shadow would more or less look alike, the other would be placing them where no direct light would "hit" them.

Kubo,..i cannot open the .ifl file (the RPC texture set) as it is not supported by octane. Your answer implies that you tried to load RPC before on octane, how did you do it..?

no, actually I don't use them, I rather prefer doing my own billboards, but there is a plugin for photoshop, I guess there you could extract the pose you want to use for that billboard and apply it either in octane or max.

kubo, thanks, but you've lost me.. lol, would you slow down a bit on this mate? how did you do it again? never use photoshop plugin, probably why im confused..

sorry lol, yeap, sometimes I confuse myself too. The things is that archivision has a RPC plugin for photoshop, there you can open their ifl file to add the whatever (people, car, tree) to your image, with that plugin you can choose which of the images (the ifl is just a container for several shots of the same object from different angles) you want to use, choose the ones that adapt to your scene, and create a png image with transparency. What RPC are is nothing more than billboards, that is planes with a image texture to fit that size pointing to the camera, so once exported they should show up as blank planes in octane (I don't currently use RPC I did try it out a long time ago, but it hasn't changed I suppouse) but coordinates for the texture should be correct, so you pick that planes material and assign the png as textureimage in the diffuse channel and the same png as floatimage in the opacity channel. It should work, but like I say I haven't test it, so if it works, or you can manage with this, please do post.
Cheers

okay np, now that you explained, i actualy did that (create my own plane) and never actualy used the rpc from inside 3ds max.

A bit of correction i'd like to make in my case here, the ifl im using does contains a set of images, but rather than shot from different angles, it shot from the same angle but different position to make the illusion that the person is "doing something". Ripping one image will only make the person static which is not what im after.

My question was, is there a way to load this series of images into one plane, i.e: frame 1: position1.jpg, frame 2:position 2.jpg, and so on,..

or am i pushing my luck..

um, I see the problem with sequential images there, um, I think that's out of my league, it easy to setup that in max, but at export it would have to point to a diferent jpg each time for octane to catch up, you might ask in the max exporter forum, the guys, kilad and [gk] are the script experts, they might find a workaround.
