Partial transparent material

perk · 6 Apr 2012, 16:20

Hi all,

It's been quite some time since I have been on here but I am back and have a question about material creations. I have created a material which is basically a type of perforated steel plate. The material I created works well in SU (I know it needs a little work but for now it does the job) The problem I am encountering is when I bring it into kerkythea the transparent potion renders as solid white. How would I go about keeping the transparent portion in Kerky?

Thanks

Hi Jeff. It works fine here. In KT the png textures are automatically imported as diffuse+clipmap material. Just check you have the "alpha channel" ticked as the picture below.

Dang. Massimo... Finally I could have felt useful...

(On top of all, I did not realise I could use the original image posted above)

You are more than useful Gai.
No need anyway to add anything. It should be all "automatic".

Ok I dont have the option for alpha channel under bitmap options.

massimo · 6 Apr 2012, 17:08

That's weird because I used the map you posted so you should have that option. Have you imported in SU the image as texture or as image?

it's a texture in SU.

massimo · 6 Apr 2012, 17:50

Could you please upload just the problematic part of your textured model? (SU 7 or below)

Make sure to select the clip map image (step 1) so that it's highlighted in green. Then also select that image thumbnail where I show step 2. The alpha option only appears then.

Here is a screen shot from Kerky and a simple model with the material

I see no model.

Hmmm...Really strange, it works just fine here. Have you the latest version of SU2KT exporter?

Gaieus · 6 Apr 2012, 19:51

Hm. Interesting. For me (also?) the material is exported as jpg, not png (therefore, obviously, no alpha channel can be found). I do not know why this is happening.

I could reload the jpg image with the png however. Copy the png to the material folder KT creates when exporting and when opening the material browser in KT, change the jpg material for the png material.

It should be the latest. I just reinstalled it 3 weeks ago. What is the latest version and how do I check my current version?

Gaieus

Copying the png. into the folder seems to be working . Thanks for the help gents. Once again you guys have proven why this is one of my favorite forums.

Plugins > Kerkythea exporter > About...

Hm. Interesting. Mine says:

SU2KT version 3.1 beta2 27th October 2007
Now I am pretty sure this is not the latest version.

True however that nowadays, if I need to open native Kerky at all, I first tweak everything in Twilight and export from there (lazy solution for mediocre rendering talents)

massimo · 6 Apr 2012, 20:05

the latest version should be here I guess.

perk · 6 Apr 2012, 20:07

HUM.

Mine is 3.0 6th oct 2007. I just reinstalled it not sure why mine would be even older than yours.

Gaieus · 6 Apr 2012, 20:14

All right. Now I updated my SU2KT plugin and it exports the material correctly as png and even the alpha is already added as a clip mask. I really do not know what I have been waiting for.
