Re: material problem in beta 4

Beta4 dont work with texture scale, this is big problem, when this problem finish.

Ok - I'll look into that, thanks for bringing that to my attention.

Re: material problem in beta 4

the only difference is the problematic computer has also SU 5 on it ( because simple jpeg imports come out as black)

I seem to find a way to temporaryly fix it though; i use texture jpeg s from outside the SU: That way i the render comes out just fine...

Re: material problem in beta 4

One of the problem I noticed in Beta 4. Is that diffuse map (when using a image) switch all the time to channel 2 instead of 1 ... As a result I have only the color of the map ... nothing else. The switching between the map on that particular project i was working on seems to appear when I change the output size of the image.

Did anybody else had that problem ???

Yep, I experience the same issue.
When trying to change the diffuse color of a vraylinked material, suddenly two channels are made automatically, one with the original texture and one with the color. However, only the color is rendered and not the texture.

Bug?

Whether there is posible, that problema maybe,that on a computer there is both skp5+V-Ray and skp6+V-Ray.

I deleted skp5 from computer, poblem still exist!

I'm not sure entirely what your saying - but you shouldn't be trying to change a linked material's read-only layer through our material editor. Since its read-only any change you make to it won't stick. But maybe I'm just misunderstanding what your saying. What do you mean two channels are made? Do you mean two layers?

Ok - perhaps this is the texture scale issue that Mado is talking about. Its hard for me to tell without being able to reproduce the issue myself.

I'm confused by the images you posted earlier - it looks to me that only the floor is mapped incorrectly, is that right? The chairs are ok?

We are not supposed to change the diffuse color/texture of a vraylinked material because it is read-only. I understand that.
So if I want to change something to the texture in Sketchup I would assume that the vraylinked material would adjust to that. But it does not.
So what is the use for a vraylinked material if it is not really 'linked'.

I hope the team will work on more automated linking because I think it is necessary for a good workflow.

My favorite workflow would be texturing everything in Skecthup and then automatically find the textures in the vray material list.
Changes to a material in sketchup (e.g selecting another texture or changing color) should be automatically updated in the corresponding vray (linked?) material.

This kind of workflow would make vray fun to use.
Otherwise it's just a pain in the *ss.

I must say in beta 4 there is some progress made on useabilty. For instance, the fact that when you add a reflection layer fresnel is automatically checked.
These are the kind of things that are usefull.

I am certain that 80% of the vraysettings can be 'preset' like that.

If Vray isn't going to be more K.I.S.S...people are going to pass.
Vray was conceived back in a time when 'all' CG and CAD software was very very complicated and only a few people could work properly with it (hours and hours of training?).

The power of vray as a render engine is still cutting edge.
The typical workflow of chaosgroups Vray is, however, extremely outdated.

"If it can be simplified, simplify!"

I don't envy you guys of Asgvis having the task to port a complex render engine to Sketchup.Tough job

No- any changes to the Sketchup material "should" appear in the linked material. If it is not showing these changes then there must be some problem I've introduced along the way.

We are going to try to make it as user-friendly as possible for our first iteration. I don't think we will be able to get to the point where everything is as easy as it should be - but we will get there in time. Our goal is to make V-Ray a much friendlier renderer to work with for those not interested in the nitty-gritty - but also allow our hardcore people the power to customize to their heart's content. It will take time, but we will get there with help from you guys - the users.

This is the problem of the rendering without textures; it seems i formatted my computer for nothing. Simply after some number of renders it gives this error in my pc. The problem is is loads some and it doesnt others; i extracted png files from SU6 files but still it shows textures at random...

Re: material problem in beta 4

ok this time i found the problem; i am sure of it. The problem is when i change the colour of the textures from sketchup material edit. When the colour is edited vray cannot take the render.

Re: material problem in beta 4

Do those files exist on your machine?

Essentially I load up all the textures in a scene into a Sketchup texture writer and then write them all out to the machine's temporary folder. So the only reason I can think of for it not loading would be if, for some reason, the texture writer is not writing out that given file.

Re: material problem in beta 4

basicly when i saw that the materials cannot load; i did similar; i loaded all of the jpeg files in the temp folder. But still the textures that have been changed colour in the 3d file didnt showed texture at all...

Joe as u know i use SU5 to render now(cuz of the problem after format), in SU5 all of the textures are in jpeg format but in SU6 they are loaded in some king of compressed file that i can open with 7Zip. I use the png file as texture in material editor.

I am not sure if i know how to open Sketchup texture writer :

When i make the editing of the texture from Photoshop(like making it darker or, changing the colour) and then save as a jpeg file, the file loads.
When i use the file origionally without any editing it also loads.
But when i use a texture and edit it on material editor in SU it cancels at render.

Re: material problem in beta 4

Ok - I'll look into it further. I suppose when Skp modifies the texture V-Ray doesn't like the format it writes out.
