Title: mayaToCorona 0.43
Post by: haggi on 2015-10-15, 19:23:30

Hi,

In this release the photographic exposure bug is fixed.

- the file texture node and the area light node now has an attribute called "No OSL". If you turn on this switch, plain Corona textures are used, what means you cannot use any procedural texture only a file node with it's placement node is recognized.

To be clear:
If you turn on this switch, then if a file texture is directly connected to an attribute, this file node and it's placement node is used for texture mapping. But it is used without OSL and OIIO, only with Coronas own texture system. Please tell me how it works.

Hey Haggi,

As show in the images attached, textured lighting in general seems to produce artifacts which are especially noticeable in bucket rendering mode.
Additionally the image gets distorted when used in an Area Light.

Couldn't check new displacement features because of Maya crashing every time I tried to use displacement mapping.

Btw I'm using Maya 2016 Extension 1 + SP3 under Windows 10 (64Bit)

Regards

Wow!
Uncheck  "No OSL" and   performance with textures much better. Thanks Haggi!
And no crashes when connect file node.

Oh, yes, I forgot to mention that the area light is a bit screwed up. I'll check displacement mapping, thanks for reporting.

No, there is unfortunatly currently no complete feature list. There something like a list of supported shading nodes if you have a look at the ressources directory. There is a file called ShaderDefinitions.txt. Here all supported shading nodes are listed.
For maya itself most features should be supported except:
- Volumes
- Hair
- Nurbssurfaces
- Particles itself - particle instancers should work

Haggi,  is possible to put a round corners in the shader?
Not comfortable always connected in bump slot.
Maybe like Vray through Add Attributes...

I'll see if I find a way. Maybe we can use a set override like it can be done with normal shading. Then all objects in the set could receive the same round corners settings.

I can approve that displacement mapping is buggy and does not work at the moment. I'm working on it.
