Quick summary of what’s below:
- 3D photo captured myself as high poly model with textures (.obj)
- Export creates 3 textures with various bits of myself and the environment I shot in scattered among them
What I struggle massively with:
- Create a low poly version without messing up the textures whilst keeping high texture detail
Long version —
Here’s the set-up:
I used 123D Catch to capture a very high poly model of myself to use as a character for animation (and maybe games).
Alongside my desired model was a bit of environment, which I didn’t need, so I deleted that, and exported the desired model as an .obj.
This resulted in 3 texture files (.jpgs) with bits of the environment and different bits of me on it.
The desired outcome:
From this high poly .obj with its 3 texture .jpgs I want to create a lower poly model which retains the amount of detail displayed in the current texture files.
What I did:
I made a low poly version of the model by using Decimate.
I then attempted to create a normal map to make the model seem a lot more detailed than it is.
- The model has 3 materials, each of them assigned one of the 3 .jpg textures: This caused problems when trying to create a clean UV map (it creates 1 UV map for 3 different textures, resulting in various problems with assigning textures)
It basically stacks the 3 .jpgs (all of them have the same size) and puts on top of it the automatically generated UV map (so sometimes one shape will call my hair, other times my trousers, as these two textures are in the same position in the .jpgs).
I then had a problem creating a normal map texture as the other 3 would lie on top of it when creating it…
Any help appreciated!
