To Unwrapping a mesh

  • Shortcut U to activate UV menu.

Select edges then use mesh -> edges - mark seam to cut the mesh on the line.
Seam means the path can be separate when doing UV unwrapping.

Unwrapping

The blue & green part means the UV mapping is in a good situation, which can be recognized by eyes.

Baking

Consider bake as a movie, you get everything prepared and play it, and the realtime render is more like a show or a theatre. It is more flexible and more attractive. But the problem is it depends on all the factors’ status.

Edit UV in external tools

I use to think that an 2D artist do painting on the flat canvas, then wrap it on the 3D model. But the true is just the reverse. The work flow is more like 2D concept creating —> 3D modeling —> UV painting on the model. (That might be only one way to do it)

  1. Save the UV image in to a file, then open and edit it in Photoshop or whatever you like.
  2. Switch mode to TextPaint mode, choose the external dropdown to Quick Ed in your default image editor. After edit save the file , then the affect appears.
  3. Save all your UV in to a UV layout to edit. After Painting on the uv layout. Reopen it in the UV Image editor. If you want to see it in texture mode , just open it in the Image editor, then switch to it in the dropdown list. Switch to texture mode to display it. If you want to display it in render mode. Make sure to create material then create texture on it, select the image to the target. Then render……While I’ll do this again and take some screenshots to demonstrate it.

Sliding and Joining Windows

Finally , I can handle it!!!
Drag the triangular towards to the direction to the TOOL BAR edge, don’t drag it to any space area.

Enable Nvidia Card CUDA to support rendering mode

I tried several time to render my model in Cycles Render, but it always display in a unrealistic feeling. And sometimes it will take long time to render. I found that if you enable the GPU rendering, it will run crazy faster than before.
Open user preference —> System —> Cycles Compute Device.

enable_gpu_render

Select the device to enable it.
Don’t forget to enable it in the inspector panel, under Render , Device to GPU Compute.
