Is in Max the reflection intensity limited too?

@Micha:

well it depends, when you stick to vray materials, the highest intensity is a 255/255/255 white in the reflection slot, which is influenced by ior in conjunction with fresnell and the refraction of the material (the more opaque, the more reflective, the less transparent). However you can also use a standard max material with a vray reflection map applied to the reflection slot and in this case you are able to boost reflection further on if i remember right…

Andy, good to know, so Vray is not the bottle neck, it’s the interface. I hope Corey will give it free.

well, i am not sure if I made it clear enough, the enhanced functionality of the reflection settings are actually part of the native 3D studio material not vray, so it is not an interface issue. Anyway I have not used this functionality for a very long time, because i am content with the vray material since it`s support for separate ior settings for reflection and refraction.

What did you mean with “native 3D studio material”? The vray engine is the same, so it should not be a problem to use higher values at Rhino too or?

… I delete the diffuse layer at glass materials. Works fine.

does this improve fresnel reflection too?

by they way i talked to a max-guy and asked him about his glass settings. he told me that he never uses fresnel, but rather controls transparency by a ramp-map. this is easily possible in max, unfortunately not in rhino i think.

My focus right now is on procedural textures…and ramp is one them. So soon enough that will be entirely possible

I’d say about 90% of the actual “VRay” in VRay for Max is available to us. A lot of the limitations is that we do not yet have interface for some features. We’re very close with materials, but we are still lacking some things.

I attached a screenshot of 3D studio. The parameters which affect the reflection are marked red. Although these settings are no vray and vray is the renderengine, they still influence the outcome…

The reflection map will be available once I have procedural textures worked out. The reason that reflection map is no available now is because its spot is taken with the vray TexFresnel. However, since I’m working on pulling that interface together I will restore the ability to put whatever map you please on it. Keep in mind, the “M” that used to be next to “Reflection” in our interface is actually the exact same “M” as is next to “Reflection Filter” now. The ability to put a reflection map on has never been allowed due to the reason above. This will all change as soon as the procedural texture stuff is straightened out. This means the user will be able to decide whether they want to put a TexFresnel on as a reflection map, or if they want a Ramp, or whatever else. I hope this makes sense

Joe, could you unlimit the reflection intensity please? Often I use now higher ior settings, but it is not what I want.

I allow exactly what VRay allows for the reflection. A color with a max of 255,255,255. If your refering to the map, that soon will be available. This is not one of the things that just requires interface.

Hello Pif,

looking at your cutout people i am wondering, did you do them yourself?

vcube,

those are 2D bitmap people from got3D. I put them on flat plane in Rhino and in Rendered viewpoer I drew polyline around them and trimmed the plane with this polyline. AFAIK V-Ray doesn?t allow texture masking using clipmaps so this was the only way haw to create true shape 2D people without white rectangle around them.

well, i thought so… I am just thinking these might be quite usefull for me too
I guess there is quite a lot of work involved by manually tracing, I wonder if there are any tools to automate this. I remember on the vray forum there is a thread to do this for opacity mapped leaves on trees, since these take insane amounts of time to render in vray. I think i will check this out.

Anyway it would be also nice if we (vray4rhino users) could maybe build a “library” to share such things, of course in this case each participant must have licenced the got 3d stuff…
This way each of us could do e.g. 4 people and they would probably sum up very fast…

I will make up my mind how we could possible do this…

best regards

… the opacity stuff can be done per transparency map now. Only one problem I have in my last tests: white seams around the edges.
