Vray Sun & Appling Textures

[Sketchrender]

How is the name of god, do you apply textures to an object with vray sun, and the phy cam, the thing is completly blown out white , and then it crashes.

And it takes for ever to render.

am I doing something wrong...?

help.

I would have to assume you are doing something wrong. If everything is blown out white your exposure is most likely not set. Crashing and long render times may be related maybe not I don't know. Your camera needs to be set up like a real camera with exposure, apeture, & film speed allowing the correct amount of light in to replicate actual film light sensativity.

Hey Philip Kelly

 

if you haven't seen this already try

I generally leave the sun value alone and instead I change the f-stop no. on the camera to get the lighting I want.

 

Try using the sunny 16 rule photographers use

 

sunny 16 rule: an approximately correct exposure will be obtained on a sunny day by using an aperture of f/16 and a shutter speed close to the reciprocal of the ISO speed of the film; for example, using ISO 200 film, an aperture of f/16 and a shutter speed of 1/200 second. The f-number may then be adjusted downwards for situations with lower light.

 

There is a discussion on the vray phys cam on chaosgroup.

In addition to the above great advice, all I wanted to say was it takes a bunch of patience at first, since there are sooo many variables and manual controls. Don't feel like you're missing one simple step if you constantly get strange results.

.....there are sooo many variables and manual controls.....

 

this is true but don't create any more variables than you have to, leave the sun and the sky settings @ their defaults control everything through your camera settings.

 

A good starter is to set the film speed @ 200 and tweak just the f-stop and shutterspeeds..... (now you're down to two variables) once you get that down then start to play with the other stuff.....

 

if you are still blowing out white, start turning up that f-stop

Sorry it is not the render that is the problem it is the viewport, I can't see if the texture is being applied correctly, ie scaling ect.

 

And at the moment I don't have time to mess around with the sun settings.

 

but thanks for all the advise, I do appreciate it.

press ctrl-L to switch your view port lighting or.... go into your view port configuration and switch it to default lighting. I always leave it on 2 default lights (instead of 1)
