Maya blinn eccentricity exported as shininess without conversion #163

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create a object with a blinn shader, defaults to 0.3 spec. eccentricity
2. Export using OpenCollada Maya

What is the expected output? What do you see instead?
- Expected result: convert eccentricity to shininess
From trial and error I found the relationship to be something like:
shininess = (1.0 - eccentricity) * 128

It seems maya's blinn is actually Torrance-Sparrow, see

- Actual result: The dae file has shininess directly as 0.3

What version of the product are you using? On what operating system?
1.3.0.788M

Please provide any additional information below.

If possible, please provide a sample file that can be used to reproduce the
problem.
