Missing object in render

[YOHKOH]

Hi, Hope you can help.

 

I am attempting to model an LED screen ceiling, however the render keeps missing out objects. See attached image.

 

The object are simply flat circles with a Vray light material, which is then distributed along a path and arrayed.

 

Can't understand it, as when I zoom in and render again the objects appear.

It happened to me a couple of times. Never figured out what it had been. I had to re model the pieces.

If I may, my I sugest a simpler way to perform that what you are modeling? Not sayin that anything is wrong, just trying to sugest a bullet proof trick, and time and file size less consuming.

have that path on which you are distributing your objects extruded, so it will be a surface. Apply a material, with just one light (one circle with a vraylight material), use corresponding alpha, difuse, etc...use mapping cordinates to repeat placing and scale al along the surface. you can use displace (vray disp) if you need the lights to come out or to be recesed.

Its not fixing that issue, but its a simpler bypass to the issue.

I hope it helps

Good luck, share results,

Martin

Thanks Chiquito

 

Test is below using a map, however is there a way to contrain the displacment to verticle only. The lights are on the ends of long rods coming down from the ceiling.

I dont know if its possible, try aplying a UVW before VrayDisp.

If that fails, theres another option but it would involve, as far as I know, a nurbs surface.

What you are looking for is a two rail sweep. You have your spline (converted to nurbs) that you would use as a path through which you will pass the shape of your ceilng (if it is a cieling. This will result in a nurbs surface.

You have a number of circles bolow, circles of the diameter your lights holes wil have, place them in plan. Convert to splice, copy. Une you will convert to nurbs and project attach it to the upper shape.

this should creat "holles" in your nurbs ceiling shape. Select the Countour of this projected holes, and extrude them. You can then have that countours copied and closed, select them again and either detach them as objects, or apply a material (vraylight)

Ill try yo make a couple of tests to see how it comes along

Thanks for the advice

 

Found out if I just render at a higher res the object are all there.

Strange, but would be useful to know why as I don't want to have to render really hi res every time. Vray proxy might be the answer to speeding things up.
