Looking for a rendering program

sojourner

If you like KT than it would seem to me that Thea is a good choice for a paid rendering engine. The same guys that develop KT developed Thea.

-2 points for not reading the original post.

You could look at Luxrender

(or costs about the same as a computer game)

I agree that the "same cost as a computer game" price point, that is, US$60, is a non-explored market. For a hobbyist, even a $99 program can be too expensive. If there were more in that price, I'd collect them like videogames.

Hey guys,
I am a long time Kerkythea user but am getting tired of the issues with it so I thought I would ask here about other rendering options. This is a hobby for me so I can't afford to really purchase a renderer. Is there anything else out there that is free (or costs about the same as a computer game), doesn't watermark, and doesn't limit the output size, or am I stuck with Kerky?

try digging some information from page below:

and after that, if you already have specific interest, try to download the free trial software.. i know that this could take some time, and maybe make you boring.. but its the best solution to get what is you need from a renderer software..

Yeah, Kerky has been acting strange for me. for the last couple months I have had 2 issues.

If I set the sky setting to background color and use a nearly black color, I instead get a bright blue background.

Or if for example I use sky color, suddenly I can't turn off some kind of global lighting. Even if I have no other lights in the render besides the sun and reduce it or disable it, the rendered image still looks like it was done with the sun at %100.

Here's the kicker, I built a new machine last week. fresh install of windows, sketchup, kerky, everything. New hardware except for the drives which were formatted clean. Start a new drawing, I still have the same issue. The only thing I can think of is that I am still using an Nvidia chipset video card and there must be something in one of the driver updates from the last couple of months.

Since KT works with cpu, the graphic card doesn't affect the render, only viewport issues could be. It's a very strange behaviour what you described. Can you post some screenshot and a sample scene, here or at KT forum?

actually I believe it's hard finding something better than KT especially if you're used to its flexibility and powerful material editor.
At least not for free!... unless you move to blender and the engines related to it like yafaray and lux

Have to agree (even one might think I am biased)! Blender has neat interactive renderer, but UI might be hard for some, still definitely worth to look if you have time to invest learning it... Lux is quite potent. Mitsuba might be worth to try, even it's pretty new, it has some interesting features There also a new educational ray tracer from the developer of Mitsuba, called Nori).

Display adapter does not affect on render result of Kerkythea. Only where GPU drivers can affect is viewport as KT uses OpenGL, but if you can use viewport and start rendering issue is somewhere else. Sorry, cannot recall hearing this issue before.

The follow images where created with just the selected only object imported from sketchup, no lights added. All renders were done using the preset "photonmap - medium + AA 0.3".

This first image all settings were default except for changing the sky to background color using red 7, green 9, blue 26. In other words, nearly black. Except for the sun there are no lights in the following renders

This image was created by just changing the sky setting from the image above from background color to sky color.

This image was created using the settings from the above image but reducing the sun radiance color setting to .4.

This image was created with the same settings except the sun was disabled.

I have attached the kerky file saved from the above images.

I think the scene is missing.

Interesting...I get the same result. I never use background or sky colors then this is the first time I notice it.
In background color mode the render shows the color at full intensity value, like you had set 1.00 in the wizard
In sky color mode, but only with Photon Map, there's kinda ambient light depending from the hue but not affected by the intensity color.
I cannot figure out... perhaps is related to echo boost version?

tridem

No, same behaviour both with 2008 and boost version

Looks like some sort of bug. Managed to recreate it too. If you load a bitmap as a spherical sky, everything is correct.
