wow thanks whaat!! Just wondering whether you were planning to have saving materials available for the next stable release of indigo/skindigo? Oh yeah and I guess this is your answer to those asking for the use of several sketchup materials on one indigo material for the purpose of texture mapping? This is one of the most perfect solutions to that problem I could think possible! I don't know what else to say!

Saving materials has never been disabled. Loading materials will not be the next stable release, however you can link a saved material by creating a Linked IGM material (change the type to Linked IGM).

(Why does no one know about this????)

thanks for the release whaat!

oops loading, that's what i meant! hmm, wow! I never new about the linked igm, thanks whaat!

hey, just wondering, but is it possible to have more than 3 custom uv sets? (is the saving of the uv set only restricted to that particular entity? Because i find that 3 is definitely enough for anything I would ever want to do with one object, but I was wondering whether it is possible to have say 3 custom uv sets on one object and another 3 on another object with different materials applied) or is this impossible with skindigo at the moment?

Thanks Whaat!

Thank you a lot Whaat!
I just downloaded this latest release, and gave it a try just to get a little more used about the new workflow and stuff. I set up a really simple scene and the result after a night of calculation is attached.
There are two light layers (a simple emitter behind the corner and the three lights in front), no specular materials. The light material of the three tubes is assigned directly to the cylinders. The spp reached has something astonishing: 1750 in 8 hours or so.

I don't know if it's because of the simplicity of the scene, but:

I mean, if that's not clear, that i expected the rendering process to be much slower than it turns out to be, using layers! I absolutely have to add something specular, now..
Btw, i noticed some kind of artifacts around the cylinders, some red spots that are not supposed to be. Perhaps it's a little bug or something. Sadly, I don't have the scene any more. The server just deleted it for it was on my desktop..

So here it is.

Actually this doesn't seem to be very fast ^^
But for interiors it maybe fine...

Just a hint about Light Layers:

Indigo does use some weighting on how much samples each layer gets. This weighting is related to the LuminousFlux of the light Layer!
I don't know if this is simply in %, but if a layer has a much smaller luminousFlux than the other(s) you can see very nice in the GUI that it evolves slower then the other(s)

The Red dots seem to be evil

everything seems to be working fine Whaat, except the dialog boxes are coming up at a smaller size than the window, causing scroll bars on the sides.

also, is there a possibility to add .exr as a material option? I know that Indigo has it, and I know that sketchup wouldn't let you add it in, but maybe it could be worked in similar to the Linked IGM way.

thanks-

What do you mean? Are you asking for the Indigo Background Material feature or are you asking if you can use and EXR file for an external texture. The latter should work but I haven't tested this.

I tried it as an external material under diffuse and phong and I get this error.

I saved the material and opened it in a text editor and this is it-

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<scenedata>
			<material>
			<name>Color_C01</name>
		<phong>
				<texture>
					<uv_set>default</uv_set>
					<path>beijing.exr</path>
					<a>0.0</a>
					<b>1.0</b>
					<c>0.0</c>
					<exponent>2.2</exponent>
				</texture>
				<texture>
					<uv_set>default</uv_set>
					<path>beijing.exr</path>
					<a>0.0</a>
					<b>1</b>
					<c>0.0</c>
					<exponent>1.0</exponent>
				</texture>
			<diffuse_albedo>
				<texture>
					<texture_index>0</texture_index>
				</texture>
			</diffuse_albedo>
			<ior>1.52</ior>
			<exponent>
				<texture>
					<texture_index>1</texture_index>
				</texture>
			</exponent>
			<base_emission>
				<constant>
					<blackbody>
						<temperature>5000</temperature>
						<gain>1.0</gain>
					</blackbody>
				</constant>
			</base_emission>
		</phong>
 		</material>
</scenedata>

Hope this helps, I think this would be a great feature!

so change the gamma to 1.0 and see what happens....

Everything seems to working great so far, whaat. Also, thanks for changing the default render settings!

Let's call a cat a cat: I believe that fireflies are a natural consequence of using bidir, say often. I know two ways to reduce their impact if I may:

- Post-process diffraction will fail with fireflies. It is responsible for the colored dots. A single firefly, without post process, concerns a single pixel.

- MR_cubic as SPLAT filter (default settings) is likely to fail as well, outlining fireflies. MN_c is recommender as downsize filter.

Hence the third hint:

For production use super sampling along with the forementionned tips, then apply post_process diffraction in a resuming session.

edit: post process filter seems to be applied before reduction, wich makes sense quality wise but ehances fireflies and takes more time to compute. [REQ-non SKIndigo specific] I suggest to add an option to force post-proc filter after resizing.

Hope that helps !
