How to choose a renderer for SketchUp
-
I asked Dennis to create a tutorial to help people select a renderer for SketchUp.
The idea was to create a non-partial guide which would be helpful in evaluating the various renderers.
I think he did a pretty good job.
Take a look: (click on image below)
The idea here was to identify things in SketchUp which look good in SketchUp but might not render properly - such as materials, transparency, special objects, etc.
He is trying to get the model uploaded to the 3D Warehouse. I'll add a note here when it is ready.
(Or go to the 3D warehouse and search for "Choose a renderer") -
Hi Al, Could you post the 3d warehouse link here? I was unable to find the model by searching 3D warehouse for "Choose a renderer". Thanks.
-
I don't think he has put it up yet. The video is very new and he said in it that he would post the model soon. I am sure as soon as it is up someone will post a link.

OK, I was just trying the (Or go to..........).

At first I was a bit sceptic about this thread, thinking it is a viral marketing trick to promote Irender, but now that I watched the youtube vid, I do think it is useful.
Other render software developers should watch this vid to improve their product. Especially in terms of setup. Automatic alpha channel rendering for instance is a nice feature, which in a perfect world should not require any setup. Apparently Podium and irender does that for you without hassle.
For me, the most important parameters in searching for a good render engine are quality and speed.

same me here... to conclude it seems podium and i render are the best candidates.

Thanks, this is a great little video.
I think that rendering is very subjective, which is why I always love to see the way people on the forum handle their renders.
One of the drawbacks I (personally) found with the the plug in renderer solutions was there ease of use kind of held me back. By this I mean I had no depth of understanding of how important the detailed settings were behind the end product. By reading posts in which some of the really great rendering practitioners were discussing the settings and getting into the actual physics etc. behind the images, and delving a little deeper, I found really worthwhile.
An analogy to this is, looking back on when the "desktop publishing" phenomena first started with the onset of computers and the early software, spawned a whole world of clip art. If you look back on the magazine world in this time period it is actually quite humorous. It took quite a while for everyone to get over the "How easy is this" phase and unleash the real potential.
So I guess what I'm getting at is it's really worthwhile digging deeper no matter what system you choose.The video helps with this giving some nice comparative parameters. -
Hey, everyone!
The model is now posted to the warehouse. Here is the link.
http://sketchup.google.com/3dwarehouse/details?mid=9e0b93c387cad06c93a794ea4e64d35bSorry for the delay but the original model was to large too load to the warehouse so I had to spend some time fixing that.
But now you can download the model and try it out for yourself! Good luck!

We tried to be careful not to mention or promote any particular rendering engine. Many people have many different reasons to prefer one of the renderers.
However, we felt that a top choice renderer should be able to process SketchUp models without special alterations by the user. When Dennis gets that model posted to the Warehouse it will be interesting to learn how the various renderers are able to work with it.
Of course you have to modify models for lighting and reflection, but you should not have to modify the basic SketchUp objects and materials to get them to show up.

Thanks Dennis.
-
I think, the proper question should be "Does the render suite that you use, have a guide for rendering a photo match?". For a user, I think it would be better, first to evaluate the need and then find a render that can deliver - someting like here.

Based on some user comments, we realized that the tutorial left out sun position, sun intensity, sky color, ground color and edge lines.
We may modify the model and tutorial to add a scene for these, or else just recommend that the user turn the sun on to make sure it works properly.

Off topic.
When looking at the video I also stumbled across this:

What about caustics, blurry reflections, dispersion, subsurface scattering, displacement mapping, motion blur, full spectral rendering, proxy objects (we really need a way to overcome the limited support of SU for high poly models), render passes, multi-light... just to keep this interesting.

The ability to render section cuts sounds sick! Sadly, I don't know how to activate that option. Here's my simple model...
And here's the resulting render in IDX Renditioner Express Free, Presentation quality:
Here's the SketchUp file in versions 7 and 6 so everyone can give it a try to see what I'm doing wrong:
simple-section-SU6.skp
simple-section-SU7.skpHow did the guy in the video do it, anyway?
Anyway, gotta go now, I'l return in a couple hours to post my findings. -

He wasn't using IDX. I don't know how to add section planes to IDX. Perhaps someone else will add a note on how to do it.
Here is your model rendered with IRender nXt (with no changes to the default rendering settings.)
Also, your IDX rendering had the sun on, or some other light source. Did you turn the sun on before you rendered it?

This tutorial was not about render features. Of course, you can compare the features of the various rendering engines to help you in your decision. There are other threads in the gallery forum about which renderers make can make high quality images.
This tutorial was about things which look OK in SketchUp, but may not render in some renderers. The underlying thought was that if you have to modify your model before you can render it (explode items, reverse faces, etc.) or remake settings over again (such as setting the sun position, or defining materials), then that adds work and editing time to the rendering process.

Ok,I checked the model from the video, and it has no section planes at all. It's just a tab that hides the upper half of the model, which has been manually sliced, so the section tab in the model can actually be rendered well in all render programs.
-
You are right - the "House Roof Off" scene does not have a section plane - just a hidden roof.
I downloaded the model from the 3D Warehouse and added a section place to that scene on the front wall, and it rendered properly with the roof missing (because it is hidden) and the front wall missing (because of the section plane). (I think I had to move the section plane to the insiide of the wall - but I got confused - because I had a hard time selecting the section plane until I had zoomed out on the model.
Dennis was not trying to fool anyone, but he ran into a problem trying to load the model up to the 3D warehouse because it was too large. He was trying everything - removing scenes (which doesn't really help), removing geometry, but finally he found that the problem was that the images he had downloaded from Google Image Search were just too long. But loading them into Photoshop and making them smaller he was able to get the model under the 10MB limit for the 3D warehouse. (At one point he tried to load a 10.4 MB model - but, sure enough, the Warehouse wouldn't load him upload it. He was under a lot of pressure, because I was running over to his desk every few minutes asking when he would have a model other people could try, and he must have forgotten to put back the section plane.
I'll have him add the section plane to the model on Monday and re-upload it. In the meantime, just add a section plane yourself and see if your renderer can handle it.
