[BUG] Compare (A > B) in/out ports change values types

[lassade]

Hi, I'm getting a strange bug when using the Compare (A > B) node. When the "True" and "False" ports are pluged with two colors, both "A" and "B" input ports change their types to Color (in my oppinion these shuld be unchanged), but if I want to compare two Floats, plug "A" or "B" with a Float node is enough to change its value back to Float (both A and B). The problem starts if I go back to edit my shader a second time the shader editor will swap the A and B ports back to Color type (since A is pluged with a const float the generated color will cast this value to float4).


Frist time I plug all the values:



generated code:

Code: Select all

float3 temp_cast_0 = ( temp_output_48_0 +  ( ( temp_output_34_0 > 0.5 ) ? _TargetFaceColor :  _CurrentFaceColor )  );

Closing, reopening the shader editor and then selecting the compare node will change its B value to a color type (float4):



thus changing the generated code to this:

Code: Select all

float4 temp_cast_0 = temp_output_48_0;
o.Albedo = ( temp_cast_0 +  ( ( temp_output_34_0 > float4( 0.5,0,0,0 ) ) ? _CurrentFaceColor :  _TargetFaceColor )  ).rgb;

The strange bit is this code generate artifacts in final result, the yellow bar in between the red and green colors should not be there.

I find also other inconsistencies, that made this same node output a single channel color (black and white) with both red and green colors pluged in the True and False ports.


Edit:

Why my wires aren't color coded?

This is my shader

Hello,

Thank you for reporting the problem, we really appreciate it. The Compare (A > B) node was created by the community, we will have to run a few tests on our side. What's your current Unity and ASE version?

Why my wires aren't color coded?

Does pressing [ W ] not toggle the debug mode?

Looking forward to your reply.

Thanks!

[lassade]

I'm using
Unity 5.5.1f1 (personal)
ASE v0.6.0 dev 01

Does pressing [ W ] not toggle the debug mode?

Yes but I have to hold [ W ] down to keep the debug active. Clicking in other window, while holding [ W ] make the toggle permanent.



The problem is some what related to DynamicTypeNode class, more precisely with its method UpdateConnection and probably UpdateDisconnectedConnection, both only works properly if the node have exact only two inputs. Having more than two input lets say 4 (in this case) makes the call UpdateConnection(3) match ports 3 and 0 types.

Every time the shader is reloaded by the editor the UpdateConnection method is called for each input port so:

0 and 1 will have the same type,
then 1, 0
then 2, 1
then 3 and 0

This was what was changing the "A" and "B" ports types to match the "False" and "True" ports respectively.

My solution will be not excute UpdateConnection and UpdateDisconnectedConnection if portId > 1.

This makes any sense for you?

Hello,

Apologies for the delay, we are currently a bit overloaded. The ASE developer will get back to you as soon as possible.

Regarding the Debug mode, you can hold W to view or double press W to enable it. It's a bit counterintuitive at the moment, we are going to change it soon to simply toggle ON/OFF when you press W.

You can find additional hotkey information in the helper window.



Thanks!
