release 0.31

[haggi]

mayaToCorona is online. It now runs on Windows8 and we have a few interesting updates.
In this release I tried to match most of the 3dsmax attributes. Some are placed in different locations where I think the maya user expect them.

release 0.31
- implemented lightShader
- implemented volumeShader
- implemented raytypeMaterial #135
- added VP2.0 for light and volume shader
- added bokeh for camera #136
- adapted the primary/secondary GI solver settings
- added file check for iesLight #110
- fixed display of last buckets problem
- keep image during render region #119
- fixed wrong exposure
- fixed wrong ramp base #132
- implemented bump mapping
- fixed shaderComponent connections
- added textureFilter

Haggi  hi!
How to use bump mapping?

[haggi]

It should work exactly like normal maya bump mapping, just connect a texture to the "bump map" connection of the surface shader. There is also an example bump map scene in the mayaToCoronaExamples maya project of the installation.

Solid release, thanks for implementing "keep" render region. It is so useful when doing test renders.

I really can't find too many small bugs, the only ones so far (including .30);

- Changing the Round Corners Radius option distorts the swatch in attribute editor and hypershade

I had a few other ones from .30 but they are fixed now (mainly coronaSurface attributes not appearing in channel box)

[haggi]

Ah, good point, the round corners does not make much sense on a sphere, I'll check it.

[haggi]

Hamburger, could you try the physical sky settings with this release? With the corrected exposure valure it should work very much better.

-Translucency don't work
-bump mapping in surface shader like vray, will be cool

-Translucency don't work

I'll check translucency. Concerning bump mapping: A problem here is that we have to distinguish between 2d (uv based) and 3d (position based - not yet implmented in mayaToCorona) bump mapping. Do you have any idea how Vray handles this two cases?

[max45]

Vray not know so deep...  maybe handles bump like mia material(mental ray). it uses same node bump2d, bump3d, but easier to connect

[haggi]

Ah, okay. I'll check it.

hi Haggi,

My problem is not the exposure, but the sun not rendering any sharp shadows.

The V-Ray sun is aligned to the same position as the corona sun - theoretically they should both render the same shadow. But no matter the setting it is impossible to get a sharp shadow.

(I didn't bother matching camera exposure or use linear workflow properly, but this does not matter)

[haggi]

Yes, the sun size problem is fixed in the next release.

Didn't you have problems creating a nice physical sky previously - non sun size related?

[Hamburger]

haggi - sorry I have not been able to test. The licence is tied to work computer and obviously it's holidays now.

Is it possible to have two licences? One for home and one for work?

[haggi]

Sure why not. Just complete the usual request info, email-requestcode etc.
