Pure_Ventrue Posted May 19, 2014 Share Posted May 19, 2014 I noticed some weird textures with Unique Grasses when I was running around Riften yesterday. I'd run DDSopt on the textures soI thought that could have been the problem. Put the original textures back in & all was well. I followed the guide for settings so, unsure why this is happening. Before DDSopt After Have I done something wrong, or is it a bug in the program, or something else I haven't considered?If anyone has any ideas, I'd be grateful. I'm stumped.

0 Kelmych Posted May 19, 2014 Share Posted May 19, 2014 Did you look at the log entry for this texture in the log that DDSopt creates when optimizing? This is often useful in determining optimization problems. Link to comment Share on other sites More sharing options...
0 phazer11 Posted May 19, 2014 Share Posted May 19, 2014 It's probably just the texture not optimizing properly, there are certain ones like blood that just don't optimize right, this can be true for certain modded textures as well, I don't know if this is the case sinc eI've never tried to optimize the mod myself. However, if you want the best quality you should go over to the Unique Grasses thread and ask the mod author about it, he frequents here and has made some updates in that thread and another recently. I'm fairly certain he saves the files properly. Link to comment Share on other sites More sharing options...
0 Pure_Ventrue Posted May 19, 2014 Author Share Posted May 19, 2014 Ok so, major apologies. It seems that it's not unique grasses after all. I followed a hunch that pointed to a different mod being the issue. I just assumedthat UG was the problem seeing as a few screenshots look confusingly similar. I'm now going through every mod I'm using trying to pinpoint the real culprit. @Kelmych: I'll post the log for it once I single out the problem spotDon't know if it makes any difference or not, I'm using 0.8 pr4. I don't recall this happening when using 0.7.4 but that doesn't necessarily mean anything... Again, so sorry for the confusion :( Link to comment Share on other sites More sharing options...
0 Aiyen Posted May 19, 2014 Share Posted May 19, 2014 Once you find the texture then try to open it up in a program that allows DDS viewing... easy to find. It looks as if DDSopt either rescaled the size of the texture, or did a wrong pick of compression. But getting a view on the texture outside of the game would tell for sure. If the texture keeps causing issues you can just exclude it from the process, or download gimp and its DDSplugin and just do it manually. Many options! :) Link to comment Share on other sites More sharing options...
0 Pure_Ventrue Posted May 20, 2014 Author Share Posted May 20, 2014 Found it. The texture is fallforestgrass.dds from Skyrim Realistic Texture Overhaul. I ran just that mod through a couple times to be sure, & yup. That particular texture comes out screwey every time. Aiyen, I ended up just dropping the whole mod. I'm using it with SMC & the textures it overwrites are by no means bad.In some cases, better actually. You can see in the screenshot it has some pretty obvious & ugly seams that just don't look right. I'm still confused as to why ddsopt would do this though? I haven't set the cap below 2048x2048 so it shouldn't NEED to rescale, & compressions on lossless. Bug in the program? Link to comment Share on other sites More sharing options...
0 Kelmych Posted May 20, 2014 Share Posted May 20, 2014 The textures I found in SRTO were fallforestgrass01.dds and fallforestgrass01_n.dds. I ran the 2K version of the mod through DDSopt and compared the original and output versions with the DDSopt preview viewer and they seem identical to me. The log said it didn't change the textures. What DDSopt parameters did you use? Did you have the "Raise foliage map ..." unchecked in "Behave"? Did you process the textures using the recent recommendations for the "Constraints" menu as shown in this figure ? The recommended constraints menu settings have lossless uncompressed format settings so that uncompressed textures are not changed to compressed (it still processes compressed textures properly with these settings). In this case the normal map texture fallforestgrass01_n.dds is uncompressed (as are many of the normal maps in SRTO), and it's possible if it was changed to compressed that the image wouldn't look correct.

0 z929669 Posted May 20, 2014 Share Posted May 20, 2014 By the look of it, DDSopt simply constrained the 2k (or 1k) texture down to something very small, like 256kb. There do not appear to be any anomalies other than pixellation. Perhaps constraints by % were invoked? Link to comment Share on other sites More sharing options...
0 Pure_Ventrue Posted May 20, 2014 Author Share Posted May 20, 2014 I followed the guide pretty closely so... Yes, raise foliage map is unchecked, yes all compression settings are on lossless (though I did that before I found the guide anyway). Constraints by %, could you elaborate on that?

0 z929669 Posted May 20, 2014 Share Posted May 20, 2014 This would not be a foliage issue, since this is not a foliage texture. The constraints tab allows you to constrain by capping to a single pixel size (e.g., 1024x1024 or 512x1024, etc. ... this would only affect size of bigger textures) OR you can constrain by proportion (25%, 50%, 75%, etc ... This would affect ALL textures) If you keep this at default setting of 8192x8192 for both compressed and uncompressed, this issue should go away I think (or use 2048x2048). It could also be the normal map though, but it is hard to tell. You might want to use the preview feature of DDSopt to look at both diffuse and normal before/after.

I don't see anything like that in the constraints tab??? Keeping it ath the default 8192 didn't do anything though.I just noted that in the preview, it clearly shows the "destination" as the pixelated texture in the screenshot. Still at 2048...

0 Kelmych Posted May 20, 2014 Share Posted May 20, 2014 Where does it show up in the game so I can see how it actually looks (vs. just using a texture viewer)? Link to comment Share on other sites More sharing options...
0 Pure_Ventrue Posted May 20, 2014 Author Share Posted May 20, 2014 I noticed it in Riften. Went in the main gate & the texture's used on both sides of the path. Link to comment Share on other sites More sharing options...

Still at 2048...The Resolution Limit in Constraints ... just open up the combobox and look at the bottom. Did you check the normal map? EDIT: LKooking again at the OP shots, this texture looks like it has some compression issues too. It also seems like you are closer to the ground in the second image ... ?

0 Pure_Ventrue Posted May 21, 2014 Author Share Posted May 21, 2014 No closer, but possible looking more directly at. What difference does it make? Yeah, have the resolution limit, I didn't get what you were saying about a percentage/proportion limit. If you're talking about the different previews to look at, there's only primary & alpha.Sorry, I'm still reasonably new to this so, still kinda feeling my way a bit. The compression issues you're seeing could be the fact that I had to save the files as lower quality jpegs to make them small enough to upload.

0 z929669 Posted May 21, 2014 Share Posted May 21, 2014 The texture appears much closer up, so that alone could cause more pixellation. You should be using the[img=http://url/][/img]tags .... not the "My Media" tool (click on the little picture icon in middle of second row in editor). Convert to jpg is fine, but upload to a file share like DropBox or Imgur and copy the public URL from those. IO can't tell what is happening iwht your texture without looking for myself. Will get back if I have a chance to do that. Link to comment Share on other sites More sharing options...
Question
Pure_Ventrue
I noticed some weird textures with Unique Grasses when I was running around Riften yesterday. I'd run DDSopt on the textures so
I thought that could have been the problem. Put the original textures back in & all was well.
I followed the guide for settings so, unsure why this is happening.
Before DDSopt
After
Have I done something wrong, or is it a bug in the program, or something else I haven't considered?
If anyone has any ideas, I'd be grateful. I'm stumped.
