=> Problems with Studio Set-Up <=

[[ popoff ]]

I`m not an Vray user , but I try VrayFR because I`m Rhino user.

There are my problems when I set-up a studio:

1) I got so "sharp" shadows ( not soft typical for GI type rendering ). Also some parts of the rendering are "burned" when the other ones are dark ?!
I think scene with GI only must look something like this :



( note scene and mats setup here is 15-20 min , all mats are procedural )

How can I get normal natural light in Vray for Rhino ?

2) Where I must add HDRI - I try for environment , but there is no result ( objects reflect their self but nothing from HDRI file ). I change the HDRI file - same thing.
Model on up with HDRI environment in 3DstudioMAX looking like this :



I found some tuts here but they are for VrfR3 , in VrR4 is different.
Even I try the same options just like on tuts my result is disgusting.
I dont know why but my mats looking much more like toon style rendering not like realistic render engine ...

... all advices are welcome

Did you disable "default lights" at the global Vray swichtes. The shadow looks like coming from this light.

For GI renderings try the starterkit at the general section. Short hint: GI env for lighting, background env for refl/refr/background until you set the refl/refr env. The GI env is available only if you enable GI at the indirect illumination options.

Micha danke for your reply ,
I did not swithch off those lights ( looks they are new in VRfR 4 ).

I`ll try the things you advice me later today ( when I back at home ).

I just trying to use VRfR the same way like other programs/3rd party render engines and result becomes not so cool :-[ ...

danke once again

Re: =&gt; Problems with Studio Set-Up &lt;=

Try the starterkit from the general section - it should allow you to get nice result in a short time.

Re: =&gt; Problems with Studio Set-Up &lt;=

... results in your starter kit are aaamazing ...

I try doing the same but if I put blured HDR for GI and other one for Background my rendering looking 100% black ( I increase GI muliyplyer - same thing ).

When I replace GI map from HDR to Sky i got this :



... this must be shiny gold mat - but there is no even trace from HDR reflection&#160; :-[

Also - corner of my studio is sweep2 surface ( look wireframe ) on rendering situation looks worst - blend surface is replaced with flat one.



... I`m alredy late for work&#160; :-\

Re: =&gt; Problems with Studio Set-Up &lt;=

Did you set the HDRI texture at environment type at the texture UI? If you forget it, I do it from time to time, than the environment is one big single colored env.

Studio ground - this is a render engine independent issue. Your mesh settings are to low. Rhino must conver NURBS to meshes for screen view and rendering. If you turn on shaded or rendered view at the rhino viewport, you should see the bad meshed surfaces too.

Short hint for meshing: set all options 0 and set max distance edge surface at a good value (example: if you are working in mm, than set 0.05 ...). Use other options if you see problems with the mesh. At the object properties you can enable object based mesh settings.

"Did you set the HDRI texture at environment type at the texture UI?"
No I dont. I just done the things acording your tut for HDRI setup ( where steps are marked with a red triangles ), btw this tut is for Rhino 3.
Hope to find where that option is ...

"Studio ground - this is a render engine independent issue. Your mesh settings are to low."
Ok I`ll try custom mesh for the ground with a low distance NURBS/cover mesh.

In VRfR3 I got better result easier :



danke for patience and support

Hi Micha ,
today I awake earlier to try the things you advice me.

I cannot fond "HDRI texture" at Vray Texture Editor - there is only "Bitmap" option ?!

My options for GI HDRI looking like this :



I just change mapping of the Environment from "mirror_ball" ( just like on your tut ) to "spherical" ( like on Starterkit ). I still got nothing more than 100% black render.

What you mean typing: "HDRI texture at environment type at the texture UI" ?
UI - User Interface ?

About studio background:
Cover mesh of Rhino did not looking like mesh rendered from Vray , I was thinking Vray is WYSWYG ( What You See is What You Get ).

best regz&#160;

Re: =&gt; Problems with Studio Set-Up &lt;=

Good, you are at the right UI and "Environment" is right. The mapping type depends on the used HDRI - most are spherical.

If you open starterkit 4 and render it, do you get a black output?

The BuildingEnvBlur.hdr is an example, how a blury HDRI could look.

... hi there ...

"If you open starterkit 4 and render it, do you get a black output?"
No Starterkit works fine - reflections and self reflections can be seen.

When I use HDRI for "GI" everything becomes black on render at my file.
I put not blured version of HDRI for "Background" to get any reflections/refractions - and there is no result ...

I cannot understand what`s my fault :-[ ...

[Micha_cg]

Re: =&gt; Problems with Studio Set-Up &lt;=

Ah, you have a problem at an other file, not the starterkit file.

Is the physical cam enabled? If yes, disable it or change the exposure could help.

What is, if you disable "clamp output" (so you get a HDRI framebuffer output) and adjust the exposure of the frame buffer (enable the little aperture icon and use the exposure control)? Is the HDRI visible at the background?

Re: =&gt; Problems with Studio Set-Up &lt;=

... I told you in my previous post: "... results in your starter kit are aaamazing ..."
That`s mean I try your stuff its great ...

I`ll try switching off physical cam.

Hope to find other things you prescribe to click on them.

HDRI is not visible in "shade view" ...

best regz

Re: =&gt; Problems with Studio Set-Up &lt;=

... yeaaagh ;D !!!
When I switch off "physical camera" reflections are seen ... nice.
Result is not so cool but hope to improve the things when replace HDRI.

Which kind of mapping is better for HDRI like yours ( used in starterkit ) - sperical or mirror_bal ?

I`ll post some renderings soon.

Thanx for support once again!

Re: =&gt; Problems with Studio Set-Up &lt;=

Mirror ball isn't so good, because a part of the 360° panorama isn't complete ....

Example: spherical -> mirror -> spherical ... a perfect 360° panorama got's typical "mirror ball" artefacts. Most this artefacts are more visible.

[[ popoff ]]

Re: =&gt; Problems with Studio Set-Up &lt;=

... some of the HDRI images are distorted - just like projected on a sphere(s) ( like your HDRI on up ).
Other ones are flat , just like this :



Should I apply spherical mapping for both of them ?

Mirror_ball makes mirror of HDRI - right ?
