Tiles: rendering vs realistic issue

[Anonymous]

Hello,

I have this issue with Revit 2017 that i could not solve in all possible ways.

The material itself has 30x30 cm relief to show as ceramic tiles.

In realistic view it shows right (check image ss2) while in render it shows weird (check image ss)

I have tried changing material asset and changing material and using image bump instead of tile bump and still the same issue.I made sure 2 floors are not overlapping and not any other floor is overlapping in other phases. i tried as well auditing the file and checking online for solutions there are none. 

Please get back to me ASAP. THanks!!

Yes but i always use it, why would it exist if it always does this? i have used it before always and never had this problem.. i tried using it in a different material not cermaic and used it in bump not relief pattern and it still did not work as well.. this is the first time such a thing happens with me. Anyway i have a due for this project today and i will use an image bump. The point was that i needed a much subtle finer lines between the tiles and not as the image you have and i don't always have to go to photoshop and make the black lines thinner to do so...

I guess there is no solution to what has happened but to wait for revit 2018 for it to be fixed.

Thank you for your help and everyone else as well

I have tried all kinds of solutions and i have used an image bump and the same problem applies.. check the image attached and you will see that the bump creates 2 bumps offset slightly from each other.. i can not seem to get rid of this problem whether it is an image bump or a tile bump..

I don't think anyone understood the problem correctly, i'll explain more:

You see in the material editor(image rrr) the material appears correctly, only when i render it appears to have 2 overlapping bumps.

Is it clearer now? so again in the material editor the sample render seems perfectly fine and in the realistic it is fine, the problem appears when i render..

I also uploaded the file if anyone has more suggestions.

Thanks

I thought you had a deadline.  No?

I think the procedural mapping function (Bump, Relief) is broken in 2017.  It could be a side effect of changing the rendering engine from Mental Ray to Autodesk Ray Trace.  Or it could be due to something else, I don't know.  I did a test in Revit 2016 with the exact settings and it works perfectly (see image below).

Until they fix it (hopefully), I suggest you not using procedural Tile, but an image for Bump or Relief mapping, as demonstrated in my previous post.

Yes I submitted my renders with the slight overlapping bump that would not be recognized by the client. You understood the problem then 🙂
Yeah i guess we will have to wait for the new release..
Well thanks anyway for you and everyone's efforts on this!

but i tried to render using bump on revit 2017 and it worked fine that is
why am wondering if something wrong with the installed revit copy . he can
try to install it again

You are using an image for bump or relief pattern.  He is using the mathematical Tile algorithm.  They are two different things.

i am using image for bump as the filr i attached before

@Anonymous  I know you did.  He did not use image for bump.  See my above screenshot of the settings.

I did uninstall and reinstall revit @Anonymous as I said before in a comment. And nothing changed sadly.
I don't want to waste more of your time but I appreciate all the efforts!

Found your tread somewhat similar to a problem that I'm having in Revit and 3d Max procedural tile map. I love the ability to generate randdom tile diferences but could not find what parameters to change to get the looks as in the image attached. Is it really impossible because of some kind of software limitations or am I missing something?

The closest I got to what I wanted in Revit, was by not tiling the tiles vertilly. If I uncheck vertical repeat the render image is correct, but as soon as I check it, as I should, the texture editor shows me the wanting result but the render image shows me something diffente (not want I pretend). That really seams to me that's a bug.

In 3d Max, I got problems too. Only could make the pattern as big as one module, if I tried to make the module width more tiles, for randdom color fade purpose, I could not make the procedural tile map to show the intended result. That could still be something acceptable but the other problem is that the horizontal gaps between tiles show up with diferent sizes. I thought we could only control one size to horizontal gaps and one to vertical ones, but it seems that 3d Max procedural tile map makes somekind of uncontrolable gap size to the limits of the module of tiling we define. That means we should allways make our tile module as big as needed not to see its limits in rendering...

Have anyone enconter this kind of problems before? I know the way to solve it is to create and use jpg, but that is not desarable if procedural maps work as they should... They are supose to be easy to edit and are less memory demanding.

If anyone can help me with this issue, I would really apreciated.

It seems to work.  I had to reduce you image size since it was too large.

A little advice: A bump map doesn't need colors, only black and white.  So convert the image to 1-bit bitmap and save it as PNG or BMP, not JPG. It doesn't need to be huge especially when it is only for a couple of tiles and repeating.

Also, your issue is different than the original question. He uses procedural tile bump, not image tile bump.

Thanks for the remark on the image size, ToanDN. I will pay attention to it in the future, but in this case the image was just to show the kind of tiling that I wanted. It would be dificult to explain it in words.

I wanted to reproduce the image in a procedural tile map and could not achieve that, so my issue is in fact on topic. Did you read all of my post? I tried to keep it as simple as I could but maybe I was not sucessul...

[ToanDN]

My apology. I didn't see the other attached files where you show the procedural map settings. I will look at it later see if anything can be done.

I can confirm this behavior.  Looks like a bug with the procedural mapping.  For the time being, the workaround is using Image mapping.

Thanks, I was afraid I was the one missing something.

Just hope that someone from Autodesk sees our posts and try to solve the bug in a future release of Revit and 3d Max.

I would really like to get this tool to work properly.
