Hi BIGFAN,
Good work

Thx you very much

Also thx for already porting mat-conversion (so i've less to do

)

1 small possible bug in "exportMaterial": you can't use the global variable matMediumType inside there as it's only represents the currently displayed material and not that one you export. You need to retrive the material medium type through "readValue". A local variable with the same name should fix it:

Code: Select all

# SSS redone by BF for phase function and skin
		matMediumType = readValue(d, 'medium.type', 1)
		if (matType >= 0) and (matType != mInclude):
			if (matType == 2) and (matMediumType == 1):

Edit: I think we had once decided that the absorption color picker should look inverted. Because the colors you absorb inside medium you can't see from outside (the object will look color-inverted). So that users can imagine how the object will look, we should invert the absorption color picker (but not the abs-sliders, this represents the correct values that also goes to xml. Only the picker color field should be inverted) IMO

or perhaps user-opinions have changed since through experiences ???

After the great job of Big Fan i have added some changes into Blendigo.
1. You can use the relative path now, but it must be enabled in fileselector
2. I have scaled down the environment map gain. It is possible now to use the map with combination with a meshlight
Hope you like it and it works fine

EDIT: reposted with correct registration name
EDIT: reposted with corrected absorption color export

Absorbtion is exported wrong (settings are ignored and simply 20 20 20 is exported for absorbtion values) in blendigo 0.8t2beta1c (and all other blendigo 0.8 exporters afaik)
I'm using absorbtion in combination with sss if it helps.

Pls fix it! Thx.

Please post your settings and the exporting result. It seems to work fine for me...

I've found and corrected the bug. Download my last version

I'm not too sure where to ask this, but I'm putting it here, because I'm using v0.7t7 beta 2c of Blendigo.

What I want to achieve is a semi-translucent milky plastic material. The material is much the same as the plastic used in miniature architecture models. It's translucent enough to let light pass through it, but not enough to see through. I liken it to the properties of milk, but in solid form.

Anyone know what I mean or have done this before? I'm using Indigo's latest stable release (version 7)

Much appreciation for any help in this regard.

use simple glass mat, but with glossy transparent and put the exponent to beyond 50...

I started out with that same concept, but I tested the material in the Blendigo material editor and it rendered black...

Many thanks, though.

BTW, I thought SSS was integral into this type of material?

Absorbtion works, but the gain is not saved and set to 100 even if there was another value first...

Also the absorbtion values are inverted during display (0.98 instead of 0.02)...

SSS IS integral. but you don't really need it in that case...
It shouldn't turn out black, except extreme energy loss...

I checked code but there's still a big mix between "matRGB" and "matAbs", i'am not sure if this works correctly like this in every case. I suppose it's better realy recheck/rewrite the diffuse-color and specular-absorption stuff.
Before both values used the same base "matRGB" with the advantage, when swaped between diffuse and specular material type, the colors for both was the same. I think BigFan splited this two colors and created a new "matAbs" for absorption color. At this moment it seems he missed small thing somewhere in code. Now last version seems to reuse "matRGB" again for absorption-color but not in every place, so there's a big mix now. We need to decide if we want two different color sets for diffuse and absorption-color or not
