View Full Version : Filling in broken or smeared camera map textures

Hey Guys,

I'm working on a VFX shot where a camera is aimed straight down at the roof of a house and then arcs out to an angle showing the house from a 3/4-view.

I have a high res plate of the house from the 3/4 view and I'm trying to work backwards by camera mapping the house and creating the roof and lawn elements for the top view from scratch with the help of a matte painter. However, I've encountered a problem....

I haven't found a way to bake my camera map to a diffuse map. I want to be able to hand my matte painter a UV layout of the baked map and have him simply paint in the missing parts. I attached the clean plate I have to work with and a pre-viz of the starting camera angle aimed straight down.

Essentially, the camera tracks down through a rainstorm and upon getting 30 feet away from the roof of the house, arcs out to show the house from a 3/4 perspective. The entire shot is about 5 seconds long.

I'm pursuing camera mapping because I have a live-action plate to match to and because the render times for camera mapping are low.

I use Maya and 3ds Max, but I'm more familiar with 3ds Max.

Thank you so much!

Thanks,

David

P.S. Cinema4D R11's Projection Man offers the ability to paint in or photoshop in textures when they start to smear and tear when the camera is moved too far. Here's a video of this in action:

The problem is that Cinema 4D R11 doesn't come out soon enough for me to meet my deadline and the demo is limited to 640x480 resolution. Do any other 3D apps have the feature to paint over broken or smeared camera mapped textures?

Didn't C4D ver10 have Bodypaint tools in it? I'd look there if you have it.

So how exactly do you combine camera maps for one final animated camera?


I haven't looked into C4D 10's body paint. Is it anything like Projection Man? Does it give you the ability to photoshop in missing camera map textures?

Yeah, you can project/paint textures onto geometry in Bodypaint. You can also do it (with a few more steps) in most 3d apps and photoshop.

For this shot you have some problems imo. First, I'd think would need to photomodel the house and some surrounding trees etc to arc over and to match this plate you will transition to, but there isn't much useful texture info in the plate.

Perhaps it's being a night shot would allow you to hide a few things but it would still need a lot of work to create the fill ins need for a clean arcing shot.
