P3D v4 importing bmp texture file without no background

#1
i got some runway marks, created them using photoshop got no background, they are transparent and I am 100% sure, when I save it as .bmp they have background, i tired using png but then it looks very different and nothing how its meant to be.

i read about some stuff regarding alpha channel but I am not 100% sure, if someone can tell me what im doing wrong it would be amazing

Hello:

Please tell us what application or utility you are attempting to import the *.BMP into.

Also, you need to tell us what you're trying to do (ex: make a G-Poly with multiple layers using transparency etc. ). :scratchch

Forgive me Gary, I should of learnt my lesson with my previous post when you was helping me that I should give more informative details regarding the issue I have, once again forgive me.

So I am using 3DS MAX 2019 and the image I am using is done in Photoshop.

So I made a quick short runway with a short taxiway so that I could practise learning UVW Mapping and Unwrap UVW.

As shown below the dirt texture has no background and I save it as *.BMP 24 bit (I read that its meant to be 32 bit but no sure :confused:) anyways I save it as *.BMP and then normally import it as bitmap into my materials and drag and drop it. It completely works in terms of showing the texture but I don't have transparent background so when I do export it to P3D it has white background.

I know you said I should stick to Sketchup but I managed to learn some stuff in GMAX that I do it within the big brother too, I can make a runway curved taxiways and successfully manage to export it to the simulator :p

If you need a bit more information Gary please do say, thank you a lot! ;)

Hi again:

Please tell us what you are trying to do (ex: make a G-Poly with multiple layers using transparency etc. ). :scratchch

Are you trying to use transparency in 1 or more layers of a multi-layer PhotoShop *.PSD file that is imported into 3DSMAX 2019 ?

If so, the simplest way to do that is to create an Alpha channel layer in the *.PSD file.



BTW: I do not use PhotoShop and/or 3DSMAX, but you may wish to review the work-flow discussed in Bill Womack's tutorial:

NOTE: Personally, IMHO, use of *.PNG with transparency is an invitation for trouble. :alert:


FYI: I use TIFF with (1) or more Alpha channels instead for all my work that requires transparency in image materials.

TIFF can use lossless LZW or PackBits compression to reduce file size as well as- or better than- *.PNG.

Such compressed TIFFs are apparently compatible with FSX / P3D SDK Resample (I'm not certain as to whether ImageTool can process those file formats).

However, 24 or 32 Bit *.BMPs are a MSFS SDK compatible format that may also be used with a maximum of (1) Alpha channel. :idea:

Your image doesn't have an alpha -- otherwise 'alpha' would not be greyed out in the Save dialog. A Bitmap with alpha will be 32 bits, with 8 bits per channel. A normal RGB image is 24 bits, with alpha it is 32 bits.
Just because your image has transparency doesn't mean it has an alpha channel. You'd need to specifically create the alpha yourself in Photoshop.

Thank you very much Gary, Sorry I took some time replying to you, means a lot pal, will definitely take a look at those links you have also kindly dropped for me to look, I would also take into a count the tips you gave me regarding *.TIF

Just tried to make an alpha channel in Photoshop and successfully have done it however I am using my brothers Photoshop which he has licence for so I can only do textures when he is around, I was thinking about using GIMP, I wonder if GIMP will be able to make me an alpha channel, I better hit off and do some research!

Thank you very much, very kind that you helped me, thank you once again!
