![](https://support.lumion.com/hs-fs/hubfs/Knowledge%20Base%20Import/17052056922012_1753908650923-2.png?width=900&name=17052056922012_1753908650923-2.png)

 

### **1.2: New Effect - Remove Background:**

The *Landscape* terrain and *Sky* can now be replaced with a solid color to allow models in a *Project* to stand out:

![](https://support.lumion.com/hs-fs/hubfs/Knowledge%20Base%20Import/17050295448604_1753908652925-2.png?width=900&name=17050295448604_1753908652925-2.png)

The option to influence the tone of the lights and shadows using the background color is also available.

![](https://support.lumion.com/hs-fs/hubfs/Knowledge%20Base%20Import/17050283127964_1753908655213-2.png?width=900&name=17050283127964_1753908655213-2.png)

When selecting the *Material ID* in the *Additional Outputs*, the background color will remain solid, making it easily selectable for post-processing:

![](https://support.lumion.com/hs-fs/hubfs/Knowledge%20Base%20Import/17050295449884_1753908657258-2.png?width=900&name=17050295449884_1753908657258-2.png)

 

### **1.3: Improved resource management:**

The graphics card (video) memory in Lumion 24.4 has been improved during real-time navigation and, especially, during rendering. Switching between *Modes* will now allocate graphic resources necessary only for the active mode, resulting in graphics card memory usage reduction of up to 40% in certain situations. The table below shows some of the differences:

![](https://support.lumion.com/hubfs/Knowledge%20Base%20Import/17083533573788_1753908658617-2.png)

### 2.2: *Photo Mode*, *Movie Mode* & *Panorama Mode*

### 2.3: *Effects* & *Styles*

**2.3.1: Move reflection control**

A new option has been added to the *Reflection Effect* that enables changing the position of the *Reflection Control Object* from the default camera location if one has already been placed in *Build Mode*.

![](https://support.lumion.com/hs-fs/hubfs/Knowledge%20Base%20Import/17050295450268_1753908663612-2.png?width=900&name=17050295450268_1753908663612-2.png)

Clicking the 'Edit' button will allow for repositioning:

![](https://support.lumion.com/hs-fs/hubfs/Knowledge%20Base%20Import/17050283130268_1753908666040-2.png?width=900&name=17050283130268_1753908666040-2.png)

The button at the top-right of the tooltip can be used to reset to the original position.

More information on how *Reflections* work can be found below:

- **Knowledge Base:** [How do Projected Reflections work?](https://support.lumion.com/knowledge-base/api/v2/help_center/en-us/articles/360003476033.json?hsLang=en-us)

**2.3.2: Option to select Optimized or Native 4K rendering**

Lumion now displays a warning alongside the option to always select between *Optimized* and *Native* resolution rendering for output at *Print/Poster resolution* when less than 12GB of video memory are available.

![](https://support.lumion.com/hs-fs/hubfs/Knowledge%20Base%20Import/17051977969052_1753908667228-2.png?width=300&name=17051977969052_1753908667228-2.png)
