jeff this may come across as a stupid question but these new production shaders for incorporating 3d objects into photographs are amazing, i love them, however i have one slight problem.
i have never done any camera matching so is this vital??
for some silly reason i was under the impression that i could just get the background image and the mirrorball image and voila, clearly not.
any chance you could detail a workflow from scratch for using the production shaders in this way???
i watched the feature videos for them but they don't mention anything about matching persepctive, they just say move your 3d object so that it is algned correctly, but am i right in thinking that we still need to go through a camera matching process???
Hello Jeff
Your knowledge in MR are great, i always check your blog every week
But i notice that in internet we have lack of MR tips for render to texture settings.
As i know it`s very hard to archive good result with MR if i want to do RTT of interior, i always have problems with FG maps and i try many methods freeze fg and mix of them but MR distribute FG samples wrong then they do RTT ^)
it would be good if you have some free time to share your knowledge in that issue on your MR blog.
Best Regards
Jammer - It is difficult to work with RTT & mental ray in 3ds Max. In fact, there are too many issues to deal with in it's current state for me to personally use it. That's just me though...hopefully RTT will see some lovin' in future versions.
sorry to pester you and this sound a bit demanding but i left a comment on april 29th, any chance you could take a look at it for me as its something i'm really struggling with
cheers, thanks for all the help you have given me so far
Yes, you need to try and match the camera angles. You can eyeball it for simple compositions. All the production examples in my gallery I've quickly eyeballed. They aren't perfect, but close enough for my test renders. However, if you're trying to build geometry onto the background plate then you'll need be concerned with more precise camera matching so the perspective aligns properly.
