Vue material distribution Tiling error

#1

Hey guys, so, first of all i just want to say im using vue 10xStream, im new to Vue, but its the main tool on my new job. Ive managed to learn some things but im having some very nasty issues that are really driving me crazy. What is happening is this: Im trying to model a lagoon, its is suppose to represent a real location so i created very specific alpha maps to reproduce the environment in an acceptable way. So im using several mixed materials and im using Texture nodes on the distribution of materials of each material. The problem im having is: When i start to add the texture alphas all my textures get destroyed and i end up with this weird tilling effect, its like a bunch of square shapes on the ground. I tried finding answers for this everywhere, I thought i had to use 16 bit images for textures, and it worked at first, i managed to make an usable file, but then i tried to use it further and it crashed, i dont know what i did right in the first time.
So the things that i tried so Far:

  • Converted all my texture maps to 16 bits
  • Tried all my texture maps on grayscale
  • Reduced my texture maps to from 8000x8000 pixels to 4000x4000 and converted all of them to bitmaps, (8bits) [I also made the same images on the same resolutions only on 16 bit mode, only this time in jpegs.]
  • Ajusted the interpolation type for all of them to Bilinear
    Nothing Worked. (I dont think i changed any tiling options since i dont even know how do to that, i did however change the scale of the materials, but i tried to recreate them using the standard 1.00 scale and it didnt work as well.)
    I Know my maps are huge but RAM is 48gbs, so i thought it could handle it
    The first time i got it to work i did it using my largest textures. And i also tried with smaller versions without success… I tried recreating the map using the same images i used the first time but it didnt work, i tried purging my memory on vue and it didnt work. Please Help me, this is kind of urgent i have work to deliver, thanks a lot guys, cheers!
    Im gonna leave a link so you guys can see the images for my viewport, a teste render and my function editor.
    http://www.tumblr.com/dashboard the name of the gallery is ‘‘vue errors’’
    P.s: ive seen some people complaining about tiling errors also but since i cant see the pictures for their issues i dont know if its the same as mine, thanks a lot for the patience guys

Are you using The Terrain Meshes from Inside Vue or did you import a mesh you modelled in another software. The only reason that can justify your using such a large map is that your mesh is imported from another software. Either way wether it is an imported mesh or a vue terrain you have to fiddle with the Image Scale and Image Offset to fit the map to the area you intend for it in the mesh. In my own case I was using an imported mesh, with grayscale maps created in Photoshop to represent different parts of my landscape. I was using distribution maps in mixed materials, and sometimes density maps to control the population of my ecosystem (grass, shrubs, trees etc…) with their corresponding grayscale maps. My grayscale maps were all 2K, and I had to multiply the x and y of the image scale by 8 to get it to tile correctly on their parts on my mesh and adjust the image offset to position them correctly. It was a try and error solution. Fiddle with these values, try to multiply x and y of your image scale by 8 ( or some other multiple), if it scale fairly ok then adjust the image offset to fit. That is the way to solve the tiling issue. The only thing i cannot tell you is the relationship between your map size and the scaling in vue. Just do a try and error thing. It will save you a lot of pain. Also remember to use object standard. Good Luck!

The thing that is confusing me the most is that i was successful at first! I actually have a working version of the file but i cant alter it through conventional ways, for example, if i want to change a setting on the material i need to change it, copy the material, reset it and the paste the copied material again, that is the only way to change it, otherwise it renders it but, before doing so, it restores the previous settings. Im using a vob terrain that i loaded to max using vue. One thing that i can see is that, contrary to what i believed, im not using 16 bit images, im gonna try to correct that! But thanks a lot for your help man, what i just dont understand is why the heck did it work once on 8000x8000 pixel images and now its not working, i didnt alter the scale the first time its just weird… I dont think its a Vue issue because i can still make functional mixed materials, but only by using only 2 materials. Im gonna try to change the scale, thanks a lot for your help. It seems to me like you used the Exact same work method that i did, im using grayscaled alphas to separate the several textures, so your solution should work for me

Im also gonna decrease the size of my alphas just to see if it will get better

I know exactly what you are saying. Same thing happened to me. The tiling in the first file that I did worked perfectly without having to fiddle with all these values I mentioned; my tiling was set to once and it worked perfectly. And I also have a copy of that file too. Also my model was done in max and imported as .obj into vue. But then when you continue to improve on your landscape by adding, removing or deleting layers or materials the tiling in Vue becomes messed up. I don’t know why, but that’s what happens. There is a video tutorial on Geekatplay where this is mentioned too. They also don’t have any explanation why. Version 6 of Vue dealt with tiling so easily. When tiling get messed up this is how I found I can solve it, just that I wish I knew the relationship between map size and scale of tiling. You shouldn’t have to spend more than an hour to get it right through the method I explained.

By the way your grayscale maps need not be that large as they are just shades of grays. Since it is not a color map I don’t understand why you are using such a large map. And you don’t have to use 16 bit images if they are just grayscale images. Jpg saved as high resolution or png 24 should do.

Thanks a lot for everything man, can i just ask you more thing, do you happen to know the name of the geek at play tutorial in which this issue is mentioned?

#8

another thing man, were you using textures just for the alphas or did you have textures for materials also? all my materials are vue s. Did you rescaled all of your textures to 8?

#9

Hey man i just want to say thank you, thank you very much. Really, nobody gave any response to this issue, you were the first one. You were right, i scaled the textures 510x to their original size o X and Y and it work, didnt even have change the offset. Thanks a lot!

I don’t exactly remember in which Geekatplay tutorial this was mentioned. If I come across it again I will post it here. By the way I am using Vue materials too. I am just using the grayscales as alpha, distribution, density or transparency maps. I am happy it worked! Pass on the knowledge. Very few people know about this.

will do! i hope this thread can help people in the future, i posted some pics it will be easier
