Title: New to KS4: Render appears completely different than Realtime Render
Post by: cmcconnell on June 21, 2013, 07:47:27 PM
Hello - I am fairly new to rendering and KS4. I am experimenting with some Hardware rendering.

My hardware looks much better in the real time window then it does after it renders. I have experimented with different HDRIs and all of teh render settings, but I am unable to get the render to look like the realtime.

Hardware.8.jpg is a screenshot of the real time.

hardware.5.jpg is the render.

Am I doing something wrong, or is this the way it is supposed to work?

Last week I ran into the same problem. Was driving me nuts.

I get this too from time to time. I can't put my finger on when it happens exactly.
Mostly differences between working window and 'advanced rendering' output.
Sometimes differences between working window and 'realtime rendering' output too.

Had this happen as well last week - ver 4 Pro.

When rendered with settings set for quality, my model had lost some reflected light compared to the RT window.  It was a noticeable difference (in a negative way).

No glass, no lighting (just an edited HDR) or anything special - just a ring model with metal material.

So I ended up rendering a clown pass (so I could make the BG transparent), then ending up taking Render > Save Screen shot in PNG format.

The screenshot had noticeably better quality than if I had rendered.

Very glad to see I am not the only one. As reassuring as that is. :)

I found I can get the same quality if I switch to a max time render. Not sure why that is.

The scale of the environment may be an issue here. We will check.

I don't know if this has been resolved or not, but I experienced issues with DOF enabled when I did the render. Image 1 shows the render with DOF on. Image 2 shows a screenshot of the render after some waiting. The latter looks better in my opinion. If I disable the DOF, the latter result(best result) will apply on both waiting and render.

Same settings and same lighting on both images btw.

Make sure to increase you DOF quality in the advanced quality settings. Or use Max Render Time or Max Samples.

I had a value of 4.5 in DOF-quality, so I don't think this causes the issue(?) But I will definitely try the the other options you mentioned as well.
