Why using External image OR Color control gives different results?

Why when using External image OR Color control inside a filter gives different results having exactly same settings?

I have been reading the External image component help and also the Color control help and have not been able to find why they do not work in the same way and give the same result when used in a filter having exactly same settings

I have seen that in some filters that I have tried to replace the color control with the external image it will not work in the same way and get unexpected and weird results and also the other way, replacing the external image of a filter with a color control instead will give also unexpected results and do not work in the same good way. This is NOT happening always and with all filters, only with some specific filters, so maybe there is some interaction with other components modifying the color control or external image result.

What are the differences between using External image VS Color control?

I thought that both could be exchanged and used to get the same result, I mean to input an image into FF, but it seems that this is not true

For example using my latest version of Alphabet Texture Creator

I have seen that when using the external image source it works right and as expected, BUT when using the color control, it will give some unwanted results in the borders as you can see below, this is an perfect square image so there can´t be a problem in placement not filling it all.
ALTHOUGH when I have gone to placement in color control and modify the tiling from None to Repeat or mirror the problem dissapears and is shown right



I will put more examples with other filters to show that it does not happen only with my filter above, it happens in many other filters and with different components combinations

Here is the above 3D extrude filter that I have modified to show this problem shown here, just load exactly the same source as external image and also inside the color control and then use the checkbox to switch from Main to Color Control and you will see that happens the above.

This filter is for FF 3.0

3D extrude External VS Color Control.ffxml

Here is the filter that I have used for the above here example AND has already this examples in the presets

I will put more examples later

External VS Color Control Scale.ffxml

Here is the filter of the above with offset and presets to show it

I have seen more filters that behave differently when using either External image or color control

External VS Color Control Offset.ffxml

Skybase In your color control setting, go to "placement" and turn change the parameter tiling from none to mirror or tile.

Yes this is what I have discovered when using color control, and you must know which tiling will give you the same result as the external image, until now I have seen that sometimes using either Repeat or Mirror is the same and will solve the problem, but sometimes Repeat will give another different result, and only Mirror will give the same result as the External image

So then External image and color control DOES NOT give always the same result with default values, so when making a filter, you must know this, and configure the placement setting in color control to get the result you want AND store it inside the preset ALSO.

There is no mention or note about this topic anywhere in the FF help that I have seen

So when making presets when you are going to submit a filter AND you want to give good results you must be careful to configure the color control with the right placement value.

With which components there could be a problem of getting different results when using external image and/or color controls?


As said above, this does not happen in all the filters, and not with any component or combination of components, so far I have seen that this happens with Scale and Offset and another filter that I still do not know which is the component that makes the problem.

It seems that this is the only problem I have found to solve the problem, and there is no anymore differences.

Skybase Quote SpaceRay With which components there could be a problem of getting different results when using external image and color controls? Anything that translates a picture (meaning all the transform components, and distortion).

Thanks for your answer, good to know

Well, I say it a lot because I have found many things that from my point of view are important and are NOT explained, commented or told in the FF help pages or in the FF wiki
