Render software advice
-
Thanks guys for the response. I have been jumping into Kerkythea a little bit. Is there any reasons i shouldn't use Kerkythea? I also am looking at the demo version of Thea. I would love some feedback on the pros and cons of these programs.
I've worked with Dynascape software in the past and they are recommending shaderlight. From the looks of it, I can tell a huge difference between Shaderlight and Kerkythea. Can anyone explain the technical differences between the two and why Dynascape would be recommending it?

Hey Guys,
Shaderlights "Replace Me" tool allows you to load massively complicated components (such as the dynascape trees) into your model without killing SketchUp.
Replace Me works by having a low poly placeholder in your SketchUp scene and then when you hit render it is replaced with the high poly version.Basically it means you get the benefits of both worlds, integrated rendering for a quick work flow and the ability to render very high poly models.
This video explains Replace Me better than I can.

Hope that helps.

In a nutshell, they have a collaboration, hence the endorsement.

Yeah i watched a webinar on shaderlight, and they explained the "replace me" tool. Most of my projects will be landscape construction in someones backyard, so i probably won't have more than a few trees. I personally don't think that feature alone would be enough to buy Shaderlight.
Right now I'm more interested in what people have to say about Kerkythea vs. a paid program such as Thea.
-
Kerkythea and Thea - in many respects - are very similar. In fact, their developer is the same person. From a landscape designer's point of view, a big difference can be displacement which is not available in Kerkythea. If this is a smaller yard however, you can live without displaced grass and use grass instances that are supported in both. Also if just a couple of trees, they can also be added with no issues similar to SketchUp as they can handle high polygon meshes much better.

Huh!? you mean not available in KT right? as it is in Thea.
-
Yes, exactly, thank you Pete (I have corrected my mistake above).

I've had good luck with Twilight renderer for SketchUp which is also a stepchild of Kerkythea.

Yes, Twilight, definitely. Especially for "starters". And you can export your model with all the settings already made to Kerkythea if you want more power (64 bit computing etc.)
-
I'm a bit of a newbie with the rendering stuff, but I was wondering what is "displacement"? Does it do a realistic job of materials like grass without having to instance it? What are good easy to use renderers that incorporate this?
Thanks,

Thanks for the input! I'm still a bit confused, why is kerkythea free, and what makes all other render programs worth what they sell for?

More or less yes. It (somehow, don't ask me the technical details) does not only apply hadows and make a surface "bumpy" like a bump map but actually creates real geometry sticking out of the surface. Think of roof tiles, grass etc. (although displaced grass will never be as "real" as instanced but for mid distance, it is okay).
There are many renderers that can do that (like V-ray) but I only have experience with Thea in this respect. Here is a post over their forum where I used a single colour image (purely for testing reasons) as diffuse and a displacement map. Then there is the resulting roof below:

Well, Kerky is a bit exceptional, that's why it's free.
There are ones that's worth the price and there are obviously heavily overpriced renderers. -
Guys like Solo and Gaieus are the experts on this stuff, but programs like Twilight at least make it easy for the novice like me to do very nice renderings quickly. There are many presets for setting up materials and lighting quickly which can be somewhat daunting if you don't have a lot of experience with it. Also it has the ability to do HDRI skies which is another feature that seems to be on the checklist. Cost is always a major factor since realistic rendering isn't a major priority for our daily architectural workflow. I am extremely impressed with some of the work I've seen on Solo's web site and I believe he uses several renderers including Thea, Twilight, and others. I'm interested in their opinions on what are good renderers based on what an individuals specific rendering needs are.

I find its GI a little weak. But that shouldn't be a concern for you, as you do mostly exteriors. Let's see ... 64 bit, studio app, free render-ready tree models, instancing brush, free ready-to-use materials, helpful community, some good free tutorials, biased and unbiased rendering. Might be just the app for a beginner with your needs. Caveat: you won't get great results straight away. Don't be put off -learning to make a decent render takes a bit of practice, regardless of the app you're using.
In short: try Kerky for a year or so.
-
Oh: don't choose a renderer over another because it does displacement. It's a nice feature and all, but it's terribly slow -in any app. And as Gai says, displaced grass doesn't look good.

Anyway, it was also Twilight for me where I started to "feel" what I am doing.

Don't underestimate your abilities my friend.

Ah, Twilight. Related to KT. Any file exported by TW can be opened in KT. Twilight is easier to use than KT. Setting up materials is dead-easy.
So, what you may want to do, is set up mats and lighting in SU using Twilight, then export, and add render-ready trees from the KT site in KT.

Well, my renders always smell sweat.

Exactly, if you really need those high poly plants. I can often get away with billboards inside Twilight though. And as long as SU can handle them, Twilight has no more issues rendering component instances than Kerky. Also it can render stuff on hidden layers (what a Godsend!)

I'll jump in with my two cents.
I use Thea at work (architecture office) and Kerkythea at home (free). They both work very well/easily with sketchup and either would work just fine for you. If you don't mind paying a bit Thea is the better program (no surprise) but you might not need it.
There are plenty of differences between the two (active development not least) but the two main items I notice switching between the two are displacement and layers. Of these, layers is BY FAR the more important. Displacement is nice, and occasionally I do use it, but it depends on the type of result you're looking for.
Professionally, the images I'm trying to get are meant to show a compelling presentation of the proposed design to the city or a client. Reasonably believable materials and colors are important, as are good shadows (especially to show depth). Either program will do that just fine. Displacement makes for longer render times and more setup. Plus, if they're overdone they look as bad as if they weren't used at all. There are some real artists who use it in their renderings but are you showing closeups that honestly necessitate that detail (possibly) and do you want to spend the extra time required? For me it's rarely worth the time.I tend to like "pretty good" renderings, that specifically establish the desired/required lighting and shadows, and then finish in post-pro (these are some great tutorials for that). It's faster and gives you good looking results, even if it's not PR.
About layers. When models start getting very large (usually when doing detailed exterior scenes) it's really nice to be able to turn off some variation of: the grass, the cars, the trees, the people, etc. It's such a basic feature but unless I've missed it you can't do that with Kerkythea.
Instead of displacing grass, I usually either use instances (very easy to do in either program) or post-pro as in the tutorial listed above.Basically, get Thea if the expense makes sense for your business. Since you're just getting it, I imagine you've been doing fine without it in the past and this is just a new (very helpful) area. If that's the case, kerkythea is the way to go; if it works well then upgrade and the workflow if very similar.
Longer post than I intended. Sorry.
