having Imposters issue 4.01

sorry to bother you all again but , Im experiencing weird behavior in 4.01 concerning the imposters that are being generated from the shape editor .  I have tried a few different settings with poles angles etc. and cant get a satisfactory result . The defaultTree imposter is the one farthest back , the big white border on the bottom of the image has been the problem . Ive pasted files directly from other folder which are behaving correctly but when I import the dae it generates these imposters . Any idea ? thank you .

this is a copy and pasted defaultTree which works great in 3.9

fyi , a couple buildings from free3d , a couple AfricaSavanna bushes , some older t3d terrain tiles , some freePBR terrain tiles (cant see them well) , and , Im making the aptera in blender 2.79

well , just in case anyone else is having this ish , seems 3.10 produces good imposter images . I use gimp to open 3.10  dds(or whatever they are) then export them to the 4.01 folder . the normal also , and generate the mipmaps .

also gives the opportunty to modify the image ie or eg or whatever , these could be a little brighter . I use a combination of gimp and materialize . TY

BTW 64 x 64 imposters 👍

The imposter algorithm is a bit flawed, imposters get shadows even though they are 2D and they get shadowed from the wrong side which makes them look too dark. I posted this issue before, but nobody cared.

Otherwise for textures as with the terrain issue, make sure they are relatively neutral brightness, so they do not turn out too bright or too dark. You can also edit the imposter image files manually, which I sometimes do, but you need to keep backups constantly and make sure they are not overwritten by the automaticly generated imposters again.

thank you , Duion , what do you say ? I guess its a math misunderstanding or an input misunderstanding but Im not having any luck . be sure and see the imposter , which is the tree farthest back of the 3 ,  near the larger bldg , it has a thick white border covering much of the lower half . this has been happening to all of my imposters . TY

You can do it in Gimp as well, but it is a bit tricky, you basically fill the alpha channel with similar colors than the shape and then delete it again, because the colors remain in the alpha channel even though they are not visible, the tool does it automatically in a more sophisticated way.
