did you make the cube with Extrusions? if so then that is the underlinning issue
for normal decal image a bit of extra space around the outside will allow you to adjust the placement on the model i.e, open it in Photoshop and make the canvas 100 pixels bigger
No I used the exsting cube in dimesnion and just chnaged the size of it. The problem is I have four different decals that need to go on four different sides of the cube. And it needs to go to the exact edges of each plane of the cube. I can't get it exact, it's either too short or it freaks out and creates artifacts spilling over to the othre plane of the cube.
are you using the magic wand to split the cude into different materials?
It's the same material just with a different image on the sides. I have pasted a render for you to see. You can see that it doesn't quite line up exactly to the plane. It's a white cube with decals. Also when I place the decals I make them the exact width and height as in photoshop as each plane is meant to be, but it always distorts the image and doesn't bring it in as it's original dimesnions. I have no idea why.
And if I follow your steps exactly this is the result. I have no idea why it hates me lol
the white edge is normal and I add blank space around my decals to correct it... distortion is what happens when you try and make decals the exact size i.e, the edges will auto wrap around the edges
also that is not square so a square decal will not fit unless it has blank space
I'm using a decal that is the same dimesnion as that side of the cube ie 380 x 270mm. When I place it it distorts as you can see from the image in the reply before this one.
can you share the Dn file?
yes the issue is the way you are trying to use Dimension... it is NOT designed to be exact in its decal placement and you can only adjust them by hand | eye, now you could ague that is a example of bad ui design (and you would be correct) but you want a decal that can be lined up and making a space around the decal image is the way you do it
your file back... the left one has space around the decal and is easy to line up... the right one is yours
I'll save you some time as its out on the right hand side and correcting that is going to make it go out at the top, bottom or left hand side
also note that making it a Jpg turns the blank space into a white boarder but the result is ok as an example
p.s, sorry for taking so long... Adobe is having issues with their servers
Thanks so much for all the help! Hopefully Adobe makes it a bit easier to do decals like this in future updates. But this helped a lot, thanks!
