Is there a flaw in the Bristol alpha channel?


Recommended Posts

Finally have my machine back up and running, and I'm trying to get back in the groove for skin making, but each time I export the Bristol's skin (I am a gimp user) it comes out super shiny. Is there something wrong with the Alpha channel, or is this template simply very glossy by default?

I use Photoshop, but I would like to help if at all possible. Could you post a screenshot of your “shiny” skin, and a similar official Flying Circus skin in the same position and lighting? You could even post your .dds file and I could look at the alpha channel in PSD. Hopefully I can help figure it out. Cheers!

Many thanks. First images is what happens when I export, and the second pair is from the default skin. Linked is the same skin, which is a simple export of the the template with no additions or alterations:https://drive.google.com/file/d/1qA1ZPDgNkvmq9xnfimJiFW7p8MebkPEk/view?usp=sharing 

 

I wonder if something might be going wrong in the conversion process from a PSD to Gimp's format? I'm still pretty new at this, and so I'm never quite sure what is my own mistake, or an error since I am using gimp rather than photoshop. I've had similar unexpected shininess from the Yak 1 template, so I know I can correct it, but if there is some resolvable issue I am encountering, better to nip that in the bud.

Hi, @migmadmarine. The good news is you're not crazy, the alpha channel is both brighter and substantially washed-out. The bad news is I have no idea how or why this happens. I suspect there must be a conversion setting or something not quite right with Gimp. Sorry, but I don't really know anything about Gimp.

 

Here is a screenshot of the alpha channel of your download:

Here is the default alpha channel:

To adjust it (using Photoshop tools) I couldn't simply brighten the alpha channel as there is a lot of missing contrast, so I needed to make two adjustments to get it close. First I needed to adjust the contrast alone by 100%.

Then, I adjusted the contrast again by 50% and the brightness by -95% to get it close to the default contrast/brightness.

I realize that these adjustments may be different or not applicable to the alpha channel using Gimp, but I wanted you to see where you would need to be to have a default alpha channel. For what it's worth, alpha channels (in Photoshop) are easily copy and pasted like any other element. I've taken "clean" alpha channels from other skins and pasted them into my work files before. I don't suppose that's possible in your case? Anyway, hopefully we could hear from a Gimp expert to get to a cause, and a solution if make ideas are useless ... S!
