Vision transparent MVR material

Recommended Posts

Hello everyone 


I am trying to move a model from Vectorworks to vision, to pre program. 

In the model I have some semi transparent PVC cloth. 


I do a export to .MVR, and import this file in Vision. 

However I don't seem to get the transparency in Vision. 


I attached some screen shots. 


Do you have a solution for this? 

Is there any god advice on getting materials to show in Vision?

Your problem is the combination of 2 issues,

The first is that Vision can't render partially transparent textures. It can do alpha map textures which will control where a object lets light through but either all the light goes through at a given point or none.

The second is that you have have used one of the procedural shaders in preparing your texture in Spotlight, if you use anything other than image (or colour for the colour shader) the texture will not export all of its data correctly for Vision (or anything else that can read an MVR).


To get the effect you are looking for you will need to use an alpha map texture of a fine mesh and probably invert the 'normals' (right click on the object in the scene graph) so that the lights interact with it correctly.


The VW university link below is to our new workflow doc that explains how to prepare textures for export to Vision when using MVR




and this is a forum thread about preparing textures for use in Vision

Hello Jesse


Thanks a lot for your reply. 

I am looking through the articles. 


As i understand it at the moment, I will need to create the texture outside of Vectorworks am I right?

When I want to make a 60% transperent screen? 


I hoped I could make simple textures directly in Vectorworks.

Correct you will need to prepare the images for the different shaders outside of VW in most cases.

Gimp (GNU image manipulation program) is a really good free free app for the basic image editing and NormalMap-online is the best free way I've found for creating bump and reflection maps.

Is the mesh image you have prepared for the transparency shader a black and white mesh?

from your screen shot it looks solid gray, which will work in VW but not in Vision


below is an example of a kabuki gauze texture and how it looks in Vision

With the texture normals inverted (to invert right click on the screen in the scene graph)

Hi Jesse


Thanks for your reply. 

It makes sense! I made a grayscale, not black and white. 


Now I made a black and white transparency shader. However it stil don't show right in Vision. 

It seems that the shader imports, but there are no transparency. 


Can you se any mistakes in my setup? 


Something is still
