One texture masking another?

Unread postby skaliwag66 » Mon Mar 10, 2014 4:12 am

I am trying to upgrade the signal head textures for the VNHRR route's searchlight signals but I am running into a strange problem.

The signal aspect textures are identical in appearance, proportions and size to the ones I am replacing them with. I am actually just layering the new texture upon the old texture in Photoshop. I save the textures to the appropriate specs which is: DXT3 ARGB, Mip Maps=7. Identical to the originals. However when I load up a scenario, the signal aspects do not appear until I come really close to the signal. Whether by zooming in or by moving close to it. All I see is the texture underneath it which is the actual head texture (both the head and light textures are separate for the searchlight signals). It appears that the texture underneath the new ones are masking it somehow. Pics explain better than words so here are three shots. One from the very point the texture disappears (starting from there and moving back there is no new texture), another shot from the point where the texture underneath just starts to mask the aspect textures (leaving black spots), and the third from the very point where the new texture starts t appear. When I revert back tot he originals, the original textures show up. very strange since I am only just layering a new image on top of the old and saving.

Can anyone suggest any thing to check and to try out before I give up. They look too good with these new textures! !*don-know!* **!!bang!!**

1. From this point as father back the signals do not appear.

Image
2. From this point the signal just starts to appear but you see the residue of the texture masking it.

Image
3. This is how close I have to be for it to show up without fault.

Thanks for any help! :D

Just as an experiment, try saving with no mipmaps. If the problem is associated with the viewing distance, it's possible that mip-mapping is the culprit. What are the dimensions of the texture? Maybe at a certain mip level, the image is reduced to just black.

Hi,
Thanks for the reply.
I'll give your suggestion a try.
The dimensions of the textures is 256x256x24


EDIT:
Removing mip maps produces this:

Hmmm, with that size, mipmaps shouldn't be a problem, but it's worth trying anyway.

LOL well my problems are solved... !*roll-laugh*!

It was an easy fix. I just used the original hi res texture files which were the exact same dimensions as the VNHRR originals and renamed them.

It was a conflict between the hi res files which were DXT1 being mixed with the VNHRR ones which were DXT3. I guess superimposing one over the other and saving causes problems.

Learn something new everyday. :)
*!!thnx!!* for the help anyway.
