Slowness with Rhino and V-Ray

[abecrow]

Hello,

I have a little problem, after the installation of V-Ray to Rhino 3D software. The installation is very well, the dongle recognized and rendering fully functional.

My problem is rather annoying: After installation, the Rhino 3D software has become slower, either loading or just when I start a new project (5 to 10 seconds to get back an empty scene).

I uninstall V-Ray and retest Rhino 3D. The software is smooth and instantaneous.

I'm on the latest version of rhino 5. Is this normal, I slow downs on Rhino?

PS: Sorry for my english

thank you
Sincerely,
abecrow

Yes this slowdown is normal because Rhino needs some time to load up Vray plug-in, however the black-screen is something odd.
You could avoid this slowdown by setting the default render to Rhino Render - and Vray won't be loaded when Rhino is started , later on you could start Vray by set Current Renderer to Vray and the same slowdown will appear because of plugin-loading.

What you are looking at is not shadow (soft one) its shading. There is two different things here. The shading is the microshadow on the surface of the material if you will, so that could appear soft. Picture this, if you light a sphere with a directional light the shading on it looks soft.

To get soft shadow you need to increase the size of your light, for example if its vray sun, then you need to increase the sun size, or if its an area light increase the UV scale of that light.
