hi!

the way specular is handled in 3d coat is very confusing to me

seems to be only one layer specular...i can not put one spec layer over previous

layer with a darker color. it seems like i can only add...i like to be able to

paint darker spec in cavitys on a separate layer.

if i load a base specular texture from photoshop in 3d coat...how can i make it

DARKER in 3d coat?

with depth and color its consistent with the control button...i get inverse

action if i have white color i get black with control..but with

specular...nothing happens.

i tried setting specularity slider to 0% even -100%....no darkness

darken brush dont work on specular...if i only paint on spec channel, darken

brush get applyed to color channel even if color channel is un-checked.

i dont know how to implement better control for specular. but to me its a shame

to have such a rubust and feature rich paint set and only have basic spec

control.

can i ask for specular color feature?

how about a separate rgba per layer for spec? maybe to expensive...maybe

2 channel per layer...1.luminance 2.alpha

or maybe make it so that if i have 0% specularity on my pen i

get no spec...black in spec texture..overiding previous value

specularity and opacity of specular in the settings for spec seems to be the

same thing right now.

also a specular roughness or eccentricity (specular spread), and a specular

amount multiplyer on each shader would be cool

and a separate inverse for the specular only would also be useful when painting

with masks ect

maybe i missed something and if so please tell me.

how does 3d coat handle specular maps. is there one per layer or one per

shader?

i noticed this this in per pixel painting..maybe it works in the other modes

this may seem like a negative post but i have to say im really impressed by

andrew and his team..andrew is the king of coders in my book! 3d coat is a

really uniqe program and i will buy it soooon :) the cavity painting on

normalmaps..WOW really powerful new feature!

Yes, you found weak place :)

With eraser.

with depth and color its consistent with the control button...i get inverse

action if i have white color i get black with control..but with

specular...nothing happens.

I can make that if depth and color disabled CTRL acts as eraser.

Possibly I will implement it. It could be done in so way: color of some layer(s) will be treated as specular/luminance (special blending mode)

One per layer, but overall specularity is just summ of layers specularity.

ahhh i see, i did not think of that!!

i think a cleaner thing to do would be to invert the "specularity %"value when CTRL is pressed...question, is the "specularity %" the amount of luminance? if i have 0% i paint black, but because of ADD mode nothing gets added? if so, then a fast fix could be to change the blend mode on spec from ADD to OVERLAY or similar...all values over a "specularity %" of 50% same as before ADD mode....anything under 50% gets MULTIPLY..problem with blendmodes is stuff from other layers shine through...some times you want to completly replace the spec..and then via layer settings tab fade out or use blendmodes. problems might occur with scene backward combability.

but a better solution yet would be to let the "opacity of specularity %" drive a alpha channel and let the "specularity %" drive a black and white channel, or color channel if you choose to implement specular color.

also in the layer settings there is already depth and color opacity...if you implement spec opacity and blendmode options too..it could default to ADD and have backwards compability too.

ok now i will find a strong place :) retopo tools are FANTASTIC! among many many other.

thanks for your fast answer and congratz on V3.1!
