Alpha channels

[jaltadonna]

Why does this do this only in planes this game well alow me to repaint there stuff but i don't understand why in alpha channels its white and i cannot edit it i need a black and white image like whats on the right

Hi and welcome to the forum.

If I understand you right you want to

1. know why alpha channels is shown only for the composition (full document, not individual layers).
   Only for pixel layers you will get a separate preview of the alpha channel.
   for vector layers, the alpha channel is not shows.
2. edit the alpha channel independent from other channel
   this is a bit more complex. To edit the alpha channel, the easiest way is to create a greyscale layer, edit the greyscale layer, and then rasterize to mask.
3. If you want to edit the alpha channel non-destructively, this tutorial might help
   I hope this answers your questions.

Probably you did not activate „transparent canvas“, or have a fully opaque layer in your document.

Okay i did it like you said and probably did it wrong i still never got a image out of it oh yes vary new to this so i have no idea what i am doing videos help me a lot but not finding any about this

[jaltadonna]

To better explain see what i have circled the alpfa channel help git rid of those but with the image being all white i can't do it

Thanks for the additional information. Sorry, I did not get what you want to achieve.

1. Do you want to use the alpha channel normally, as transparency value?
2. or Do you use the alpha channel for something else? 
   If yes, for what purpose? Z-buffer / z-axis (pseudo 3D), another texture channel, …?
3. what to you mean with „get rid off“? If the alpha should not be shown as white - which color or grey level or texture should be there instead?

If English is not you native language: you can use your native language, if this is easier for you to use.

i need this in alpha channel to look like this something with the planes it wont do ships it well, and when it shows i paint the hole thing white and  thos spots go away.

i am english but do not understand what i read it looks like you left out some steps when i do what you instructed me to because it did not turn out like what i need.

The erase brush is the tool intended to delete from pixel layers. Essentially it reduces the alpha value.

[NotMyFault]

steps to copy/paste an image into the alpha channel

1. have the source image prepared as pixel layer (the ship wreck in the video)
2. use channels panel
3. create spare channel from one of the color channels, e.g. red
4. select destination layer (should be pixel layer, the black/white gradient in the video)
5. use channels panel, scroll to spare channel created in step 3
6. use right-mouse, save to pixel layer alpha

i want to thank you for the video i have not had time to do anything if i can do it i well let you know thanks so much for your help

[NotMyFault]

You are welcome. 

[jaltadonna]

just in case but don't think it matters but my image are tga and i got it done the way you told me but one problem i need it on the same image but anyway this is what i need it to do and look like the one on the left. Photoshop does the same thing so this is no different. 

I am not sure why or what the different is one is a ship the other is a plane so i don't get it.

[NotMyFault]

Any chance you can upload the actual files (.afphoto) ?

[jaltadonna]

there it is i want to remind you that i am trying to do those bad spots that i call paint peel and maybe you can not do it with the plane i have no clue, but you can with the ships.

I paint them and in ships in alpha they go away but plane i am not able to do that or would there be another way no one i have asked about how they do it they don't tell me anything about how they do it. i well be driving home tomorrow so i well check if you need anymore information.

I really not getting

1. what you want to achieve
2. 2hy you are trying to do this on alpha channel

what exactly are are „bad spots“? Those lighter areas on the wing? To get rid of them, I would normally use inpaint brush, and don’t touch the alpha channel.

This would look like below.

If you want to create dark spots on alpha channel:

1. add a mask layer
2. just use the erase brush.
3. when you export this as tga, it will be black on the erased pixels.

this would look like below

What i want is what i have circled those spots gone not there i want my plane to look like new like the other picture maybe i can not do it in alpha

Ok, that is clear now.

The Alpha channel has nothing to do with cleaning up those areas.

You can use the patch tool or inpainting tool to clean-up those areas, as I have shown.

Thank you so much the inpainting worked but i had to do it with another file the have witch is the N file other wise those marks were still there even if i paint over them in the game it self, so using that N file i got rid of them there and them paint over it with the other file, i have no idea how they do it in photoshop no one explains anything when i asked but this way i think workes fine.

[NotMyFault]

The file shows semi-transparent pixel all over the canvas. Maybe the layer opacity has been reduced ?

As long as I don’t understand for what purpose the alpha channel is used, I can’t give any advice.

If you can upload the actual file, I can try.
