A list of missing features / bugs etc.

[geejay]

As I start to use the 2.5 exporter I often find something that is unclear or missing or might be a bug. Instead of creating a thread for every issue I will throw everything in here:

- No option to set vignetting in physical camera.

- Can the bucket size be set?

- No texture preview in VRay mode, when Blender is set as render engine the texture panel is broken, only mapping and influence is visible

- Is there a way to create a shadeless material that is not influenced by lighting at all and does also not emit light?
So just a billboard that displays the selected color/texture as loaded.

1. added

2. You can, but it doesn't have GUI by now: Outliner -> Datablocks -> Scene -> V-Ray Settings -> RegionsGenerator: X & Y define bucket size


3. There is no such bug in 2.55. I'll update builds after 2.55 public release.

4. AFAIK no. May be you can do some fake.

I think it may be a good idea, as long as it is a kind of "to do" or wish list for Andrey.
(I'm sure he is the most aware of us all, what has or has not been implemented.. )

And I'd also suggest giving unique growing number to each mentioned problem/issue so that Andrey can naturally and description-less refer to them.

Thanks!

Perhaps some sort of bugtracker / to-do tracker? Like for Blender but a simplified version.
So that we can also check if some bug has been mentioned already instead of making a new topic each time...

You could use github Issue tracker: http://github.com/bdancer/vb25/issues
I already start adding some todos there.
You could also use Gist (http://gist.github.com/) or pasteall.org for error-reports for issues.

Regarding the shadeless material, in Maya the equivalent is the surface shader, which VRay for Maya supports. If we can find out how this is translated it might be possible to do the same in VRay standalone?

Re: A list of missing features / bugs etc.

Ok, I'll research this.

Re: A list of missing features / bugs etc.

Some bugs/feature proposals:

- the preset button for irradiance map don't seems to be working here, it won't change other fields.

- some objects are hidden in the 3dview when the frame buffer is open. If you pan, zoom, or even in the edit mode the still invisible. They "unhide" after the framebuffer is closed.

- sometimes blender crashes when trying to render with auto-export meshes enabled. I'll do more tests tomorrow to see a pattern.

- camera "guess vertical shift" feature like in 2.49 exporter

- apply a diffente material to back faces of a two sided material. (usefull for leafs)

- maybe could be usefull having a basic interface for mixed material. so for simple cases you don't have to create a node setup for it. For advanced editing you still able to use nodes.


Great work Andrey!

Done.

This seems to be a Blender feature.

Yep, I know about this - still can't fix.

Done.

I'll think about it.

Re: A list of missing features / bugs etc.

Some little things I found these days as I started to test the 2.5 script(great work so far!)

It seems that node mixing is not working with nested nodes.
I mean,if I have 2 materials attached to a mix node(mixnode1),another 2 materials attached to anohter mix node(mixnode2),and the output of
mixnode1 and mixnode2 attached to another mixnode(misnode3),the result seems wrong(it gives a default gray material even if every material is colored)

And it seems there is some problem with texture filtering(not sure if it's a problem with the exporter of with vray itself)
As far as I can understand in the exporter the textures use the summed area type of filtering,but with some textures(highres) it gives really bad result(no filtering at all).
Replacing with a mip map filter it works well,so there is some option that need to be tweaked in order to use area filtering with high res texture somewhere)?

And do you have considered for the future to use(only for geometry) the hexadecimal lists?(at least as an export option,I don't know how hard it could be to do or if really useful but maybe it allows a more compact storage of geometry,and I'm not sure people will be editing geometry lists by hand anyway)

Thanks for the hard work.

Yes its a bug. It works only for 2 materials now.

And it seems there is some problem with texture filtering.

Yep, I should add gui control for filter type.

And do you have considered for the future to use(only for geometry) the hexadecimal lists?

I want to use them, but still have no response from Chaos Group about its format.

Re: A list of missing features / bugs etc.

Thanks bdancer, I found also another 2 little things about maximum and minimum values for parameters.
The phase parameter for the sss material goes from 0 to 1,as far as I know it should go from -1 to 1.
And also for the sss material it's not clear to me why the diffuse weight parameter goes from 0 to 10.

Re: A list of missing features / bugs etc.

i feel a lack of procedural textures (clouds and noise) - especially for plastics with small facture
will it be possible to use them in vb2.5?
cheers,

Re: A list of missing features / bugs etc.

FB3000, its possible to have vray alternatives to this textures or i also have some plans porting this textures, but not very soon.

Re: A list of missing features / bugs etc.

Hello,
What do You mean by "it's possible to have vray alternatives" ? are they already in vb25?
cheers,
