After a day working with Vray, here my wishlist:
I would like...
- ... to refine my model during a rendering
- ... to resize the progress window
- ... to use the Rhino color wheel for color selection everywhere
- ... to use a simple transparenty option like the default Rhino rendered viewport material
- ... to see a smooth interpolation if I downscale the frame buffer window
- ... to use a global gamma option (or is it somewhere?)
EDIT: here a complete wishlist from the thread. First: thank you for the released wishes.
Some open wishes I wish to use every day and I have marked with (!). Maybe, this wishes could get more attention.
+ ... to refine my model during a rendering (solved)
+ ... to resize the progress window
+ ... to use the Rhino color wheel for color selection everywhere (solved)
+ ... to use a simple transparenty option like the default Rhino rendered viewport material (solved)
+ ... to see a smooth interpolation if the frame buffer window is downscaled
+ ... to use a global gamma option (or is it somewhere?) (solved)
+ ... I miss a blur option for the HDRI GI environment. (solved)
+ ... I would like to see if the material preview would jump from the previous preview to the new refreshed one. (solved - GI can be disabled)
+ ... object based visibilty options: invisible for camera, indirect light, lights, reflections.
+ ... no automatic material preview (solved)
+ ... material preview scene need a in reflection/highlights visible light (!)
+ ... independent global refraction/reflection disable.
+ ... a backface culling (!)
+ ... exit color for reflection/refaction
+ ... and I would wish a more compact design of all the global options.
+ ... a "north" angle control for HDRI environment, so that the environment can be turned around the scene. (solved)
+ ... background image - an image fill the viewport background complete and is working like a big textured plane in the background.
+ ... independent global disable maps for the different map types
+ ... a synchronize button for the GI environment and the background environment path (!)
+ ... a stereo vray camera. This camera type could render two eye views side by side in one image
+ ... I would like to use relative texture paths (page3)
+ ... portal area lights in non GI mode for natural colored lights
+ ... support of integrated alpha channals for texture maps (!)
+ ... if distant lights would shine trough light portals (solved)
+ ... a gamma control independent from the color mapping mode (solved)
+ ... I would like to choose between, that invisible lights are visible in reflections or not. Current invisible lights are visible for diffuse surfaces, but not for reflective surfaces and this looks some times strange. (page 4) (!)
+ ... It would be good, if the progress bar of the render progress window is at the top of the window instead the bottom, than I could move the window to the right upper rhino inteface corner, so that only the progress bar is visible. Now I can not find a good place to place the render progress window, so that I see the bar, but not the whole window. (!)
+ ... very useful would be a drop down list of a releative viewport sizes for the output menu - 25%, 50%, 75%, 100%, 150%, 200%, 400%. (!)
+ ... clip planes or walls "invisible for camera" (workaround possible - User tutorial D)
+ ... some times I start my scene with the basic rhino materials. Later, I decide to use the vray material and press "create". It could be nice, if the vray material would based on the rhino material - important for me are color and texture.
+ ... image projection feature for spot lights
+ ... IES lights (!)
+ ... I would like to use an expontial mode with an option that allow to continous shift to the linear mode, like the Maxwell "burn" option. (solved -> Reinhard color mapping)
+ ... I miss to disable maps of selected materials temporary. I wish, each little texture "m" should get a flag option befor the "m" like the bump map option.
+ ...It would be nice, if I could control the light angle per a numerical control like I can do it for the hardness now (!)
+ ... assign materials from mat editor (solved)
+ ... it could be good to get a "symetrical" option for tiled textured
+ ... It could be great, if VfR would support a "camera projection" for textures. The RCM mapping tool dosn't do it and the last info from the McNeel team: not planed. (!)
+ ... I miss a "render selected" command. Selfmade scripts are to slow for large scenes.
+ ... I could be nice to get the function "delete unassigned materials" at the right mouse button menu (solved)
+ ... Important: if the user delete a material, a warning should popup, if the material is assigned to an object. (solved)
+ ... maybe, assigned or unassigned materials could be special marked. For example: the letters of an unassigned material name could be grey and not black.
+ ... a less saturated color for the blue sphere (or disk) signs of the materials. The blue looks so strong.
Could you use this smalls signs to show extra infos like -
green ... anything is ok
red ... texture path is wrong
yellow ... unassigned material
+ ... multiselection of materials could help to delete or duplicate a set of materials
+ ... double click on a material in the browser (material properties -> browse) and the material is assigned and the browser is closed (solved)
+ ... it could be nice, if each material preview would be saved and if the user click on a material, the saved image of the material would be shown
+ ... workflow wish: if I click on "scene material" and create a new material, the new material could be selected, best in "edit the name mode".
Current weak workflow: the "scene material" is highlighted and I must search the new created material in a long list of materials.
+ ... the texture multiplier could effect the texture preview. (solved)
+ ... in Rhinoman is an option that I would like to set at the camera properties of VfR too: "get viewport focal distance". So I can fine adjust the focal distance based on the viewport distance. Maybe a small "refresh" button could do it. (page 6)
+ ... more functions to mix two maps like multiply and addition. At the moment only "blend" is implemented.
+ ... map control for the reflection options anisotropy and rotation (!)
+ ... disable GI for the material preview or disable show GI pass (solved)
+ ... ... if the QMC GI is used as primary engine, than the bounce control should be grey out (solved)
+ ... If I press at the map "m" than default map type could be bitmap. I suppose so that is the most wanted type and "none" the never wanted.
+ ... the default reflection map type could be "fresnel"
+ ... "Reinhard" and burn 0.8 should be the default color mapping. If the user need "linear", he can set burn 1 or if he like "expontial" he can set burn 0. So the "reinhard" type is universal.
+ ... if the user select an object with an assigned material and use "create" of the material propeties page, than the new material should be assigned to the object
+ ... general Vray wish: a downscale texture option. Example: I have a collection of high res textures, but often low res could be enough. I don't like to save downscaled copies. (page 7)
+ ... physical environment system with sun
+ ... change the DOF aperture parameter from rhino units to lens F-stop units
+ ... a vignetting option for the camera
