Title: How to use Corona Tiles
Post by: zules on 2024-02-28, 16:36:16
Hi there,
first of all thanks for implementing Tiles, it's very useful.
I guess you copied Bercon Maps system as I got the same problems with your system as with it by the past.
I'm struggling to have controlled effect and I really need explaination.

1st : mapping !
whatever I try, it's impossible to get result for wooden cladding on wall or surface. ex. planks01
with ou without UVWmap mod, with or without Use real worldscale on both UVWmap mod or Tiles map none of them is giving a clean cladding.

2nd :
displacement on geometry corner, are.... liquid with an effect i got with Bercon too ex. liquid corner & lc2 3

How to deal with that ?

Regards,
JG

Try using world size displacement and lower the value till you don't see any jaggy ness.

You can do this by going to Render Setup>Performance>Displacement

subdividing the mesh or applying some support loops in the chamfered areas can help too.

If the issue persists, try starting a ticket with us along with the scene file.

Well, I used world size as I couldnt get untriangulated result with px screen size : it doesnt work.
I use it through coronadispmod
I subdivided the mesh of course, with subdivide mod in 10cm triangles so a LOT of triangle on the total geometry.

Did you read Corona tile map documentation in the Chaos help portal? If you have correct UV mapping, there's nothing complicated to setup tiles map working, really. https://docs.chaos.com/display/CRMAX/Corona+Tile+Map

Check if your UV mapping is correct, try to render material without displacement and see if distortions disappear.
Try to add small chamfers to the edges and see if that helps, or if chamfers are already there, try to remove them.
Render close up view of distorted areas. If close up looks good, then you need to tweak displacement settings (decrease displacement size). If distortion is still there, then the issue is most likely with the mapping.

Thanks :)

I think UV are correct as it's a Revit model with UVWMapClean+ResetXform Mod on it, then EditPoly + UVWMap Mod on top.

I will check with and without displacement soon :)
